Condensation is the change of the physical state of matter from the gas phase into the liquid phase,1: A material that does not let heat and electricity travel through it easily is known as an insulator.

2 :Some of the common uses include Electrical insulator hinder the flow of electron or passage of current through them. So, we use them extensively in circuit boards and high-voltage systems.

Solid, Liquid, Gas. 
solid is a hard material. 
liquid can take the shape of any thing.
gas is  is a naturally occurring hydrocarbon gas. 

Evaporation , Melting, Condensation, Boiling, Boiling point. 
evaporation : Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.

melting: transform from solid into liquid .

condensation : Condensation is the change of the physical state of matter from the gas phase into the liquid phase.

boiling: Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point. 

boiling point: The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.

They are reversible changes that do not involve changes in matter's chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporisation There are two types of change in matter: physical change and chemical change. As the names suggest, a physical change affects a substance's physical properties, and a chemical change affects its chemical properties..]]> 2020-07-07 04:26:28 UTC https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648879110 Muhammad Abdul Hadi https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648879301 the temperature at which a liquid boils and turns to vapour.the temperature at which a given solid will melt.What is an insulator? A material that does not let heat and electricity travel through it easily is known as an insulator. In many situations, we want to trap heat and slow down its flow, or stop the flow of electricity and prevent electric shocks. Plastic, rubber, wood, and ceramics are good insulators
Three states of matter are
1. Gas
2. Solid
3. Liquid

GAS
(1) they are easy to compress,
(2) they expand to fill their containers, and
(3) they occupy far more space than the liquids or solids from which they form.

SOLID
(1) It has Definite shape,
(2) It has definite volume
(3) It has definite melting point, high density,

LIQUID
(1) It has indefinite shape
(2) It has Volume
(3) It is more dense than gas

Evaporation:
When liquid gets heat it turns into gas.
Condensation: 
water which collects as droplets on a cold surface when humid air is in contact with it.
Melting Point:
the temperature at which a given solid will melt.
Boiling Point:
the temperature at which a liquid boils and turns to vapour.
Boiling:
at or near boiling point.]]> 2020-07-07 04:26:51 UTC https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648879301 Shahzain https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648879395 Ans: An object that cannot easily let electricity or heat pass through.  They are helpful in our daily life because the walls are a heat insulator and do not let heat from out side come in our room and the plastic sockets and buttons do not allow electricity  to pass through so we don't get shocked when we turn on the lights. Walls, wood, cotton and cloth are good heat insulators.

Ans: The three states of matter are solid, liquid and gas. Solids have definite shape, definite volume and have densely packed particles. Liquids have definite volume but take the shape of the container and have loose particles. Gases have no definite shape or volume and have particles that are far away from each other.

Ans: Evaporation means when the water turns into its gaseous state by sun light. Melting means when a solid gets too hot and turns into its liquid state. Condensation means when the water in the air as its gaseous state or water vapour looses its heat to a cold object and turns into a tiny water droplet. Boiling means when the water starts to bubble and evaporate because of heat.

The measure of a material's ability to conduct energy through it is called thermal conductivity, represented by the Greek letter lambda , Λ. Insulators aim to prevent the transference of energy,..
Wood, plastic and air are some of the examples of heat insulators. Gases are poorest heat conductors. In other words, they are the best heat insulators. Air is a mixture of gases. This is why air is a good insulator.

solid,liquids and gas are the three states of matter we use them in our daily life like cube of ice bloon filled with gas and doors made up of solid]]> 2020-07-07 04:30:38 UTC https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648881374 farham hafeez https://padlet.com/naureentariq16695/nenk470ed8ezroji/wish/648882519 Q2: 
Solid, liquids and gas are the three states of matter.
Materials which we see in our daily lives such as ice-cream, chair, water etc. are made up of the matter. Matter can be classified as solid, liquid and gas on the basis of inter-molecular forces and the arrangement of particles. These three forms of matter can be converted from one state of matter to another state by increasing or decreasing pressure and temperature. For example, Ice can be converted from solid-state to a liquid state by increasing the temperature.

A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators. Compare conductor. 
2. Matter can exist in one of three main states: solid, liquid, or gas.
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.
Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.

But, matter on Earth exists mostly in three distinct phases: gas, liquid and solid. A phase is a distinctive form of a substance, and matter can change among the phases. It may take extreme temperature, pressure or energy, but all matter can be changed.

There are six distinct changes of phase which happens to different substances at different temperatures. The six changes are:

  • Freezing: the substance changes from a liquid to a solid.
  • Melting: the substance changes back from the solid to the liquid.
  • Condensation: the substance changes from a gas to a liquid.
  • Vaporization: the substance changes from a liquid to a gas.
  • Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
  • Deposition: the substance changes directly from a gas to a solid without going through the liquid phase.
  • boiling point(Noun) The temperature at which a liquid boils, with the vapor pressure equal to the given external pressure. Freebase(3.00 / 1 vote)Rate this definition: The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.

    • [boil] verb (used without object) to change from a liquid to a gaseous state, producing bubbles of gas that rise to the surface of the liquid, agitating it as they rise. to reach or be brought to the boiling point: When the water boils, add the meat and cabbage. to be in an agitated or violent state: The sea boiled in the storm.

Conductors are the materials or substances which allow electricity to flow through them. They conduct electricity because they allow electrons to flow easily inside them from atom to atom. Also, conductors allow the transmission of heat or light from one source to another.
