1) Thermal energy is the total kinetic and potential energy of the particles in a substance.

2)As the temperature increases , the kinetic energy increases and the faster the particles of an object move.

3) Melting is the change of matter from solid state into liquid state .

# data[].attributes.custom_properties.D51pO3-s
Some substances freeze at high temperature. Such as wax ; which freezes at 63°C .

# data[].attributes.body
1.That the change of state from liquid to solid is called Freezing.

2.That there are two main types of vaporization : evaporation and boiling.

3.That thermometer registers a higher temperature when particles move faster.

# data[].attributes.custom_properties.D51pO3-s
the most interesting thing that boiling involves an increasing of thermal energy and the freezing involves an decreasing of the thermal energy.

1- The melting  point and freezing point they melt and freeze in 0 Celsius        2- the thermometer is the measuring tool of the temperature and the degrees Celsius and Fahrenheit.           3-there r two kinds of Vaporization they r boiling and evaporation              4- the difference between steam and water Vapor is the steam is visible and the water Vapor is colourless

Melting change of material from solid state to liquid state

Freezing change of material from liquid state to solid state

Vaporisation.

means change from liquid to gas, it has 2 types.

1_ evaporation..it takes place at the surface of the liquid at any temperature.

2_Boiling..it takes place below the surface of the liquid and at the surface as well..it happens only at boiling point

Each substance has a certain boiling point.

1. Air pressure is less dense in higher elevations

2. Air pressure is also named atmospheric pressure

3. Pressure= force/area

Learned,

1_There are two types of vaporization: boiling and evaporation.

1_The boiling point of water is 100 celsius.

3_The faster the particles are moving , the greater their kinetic energy and the higher the temperature of substance.

# data[].attributes.custom_properties.D51pO3-s
Vaporization is when liquid change into  gas . The boiling point is 100°c . Melting occurs at a specific temperature. 

# data[].attributes.body
1-thermal energy is the total potential and kinetic energy of all the particles in an object or substance.

2-if the temperature increases the thermal energy increases and if the temperature decreases the thermal energy decreases.

3-freezing point is the temperature at which it changes from liquid to solid.

1-The pressure =force /area

2-condensation means :change state from gas to liquid.

3-the air that surrounds you that apply pressure on you is called atmospheric pressure.
