Particles is the universal term used for small building blocks of matter such as atoms, quarks and molecules. These particles interact with each other by pulling towards each other making them always mobile. Heat is a form of energy. It tends to give the particles more power and tends to separate them. This is why gas particles are more out of control than the other 2 forms of matter. Liquid stays in between with an ample amount of room for particles to move around causing liquid to not have any shape. The particles on a solid are very bunched up and only tend to vibrate. This is why a solid has its own shape and the shape cannot be changed. A liquid doesn't have its own shape but cannot be compressed. A gas doesn't have its own shape but can be compressed. Overall the particle theory is the theoretical explanation for the interaction between particles.]]> 2018-01-04 04:09:37 UTC https://padlet.com/826142/uuns7g2cxnlw/wish/218670086 826142 https://padlet.com/826142/uuns7g2cxnlw/wish/218670464 Heat is the cause for change for matter and it is produced in many ways. The main way heat is produced is from our solar systems star which is the sun. The sun gives off heat so that the environment changes due to the heat from the sun affecting particles in that particular environment. This is why places that have a hot climate tend to have liquid water and places with colder climates have water that has been frozen. Another way heat is produced is from radioactive decay. Radioactive decay defines as the ability for an unstable atomic nucleus to give off radiation. This is what creates heat beneath our earths surface. Another way heat is produced is from mechanical energy. Mechanical energy defines as the ability to store or to move an object. As the object moves it creates heat. This is why we feel hot after a work out. Another way in which heat can be produced is combustion. Burning something causes heat and thermal energy. Another way heat can be produced is by friction. When ever 2 objects rub against each other, the mechanical energy causes heat and whenever their mechanical energy is combined alongside the exchange of protons and neutrons. Last but not least, we have electricity. Electricity, if strong enough can cause sparks that cause heat. Large forms of electricity such as lightening cause flashes and bolts of electricity that is so hot that it burns through air. Overall heat is the cause for change for matter and it is produced in many ways.  ]]> 2018-01-04 04:16:37 UTC https://padlet.com/826142/uuns7g2cxnlw/wish/218670464 826142 https://padlet.com/826142/uuns7g2cxnlw/wish/218882494 Particles are always moving around, how fast they are moving around depends on physical state of the matter its self. ( the space between the particles make the speed of particles vary) Eg. the particles in a solid would have limited movement to only vibrations and not full movement. Liquids on the other hand are made up of particles that are spread out enough that they are able to move around slowly and due to the particles being spaced out in this manner, liquids don't have their own shape unlike a solid and cant be compressed like how a solid cant be either. A gas though can be compressed and doesn't have its own shape as well. Gas particles are extremely spaced out meaning the particles can move way faster which means it can easily spread apart like neither a solid nor a liquid. The reason why these states of matter start off from barely moving, to moving all over the place is because of the temperature of the environment that they are in. Heat=energy and energy is what powers the particles more. This is why when the temperature goes below 0 degrees Celsius, it causes water to freeze and when it goes to 100 degrees Celsius, it turns into steam. Heat causes the particles to spread apart while heat loss causes it to come together as there is a loss in energy.]]> 2018-01-05 04:03:21 UTC https://padlet.com/826142/uuns7g2cxnlw/wish/218882494 826142 https://padlet.com/826142/uuns7g2cxnlw/wish/219053569  When heated, the particles tend to spread out causing the volume to increase due to the access to more heat which is a form of energy. Energy makes the particles move faster and space out. Therefore it affects the particles to spread out. This is why mercury on a thermometer goes up when the temperature does too. Overall, when heated, the particles tend to spread out causing the volume to due to the access of more heat which is a form of energy. ]]> 2018-01-06 00:32:59 UTC https://padlet.com/826142/uuns7g2cxnlw/wish/219053569 826142 https://padlet.com/826142/uuns7g2cxnlw/wish/219056520 Overall the particle theory is a theory that helps us understand our world better. It helps us to realize that the universe is a big place with small things in it. It also helps us realize how much the universe that we live in is changing all the time. The particle theory teaches us so much about what is going on around you. How does the ice that you put in your soda freeze? How does steam from an old train engine become steam from water? All of these questions are answered by the particle theory. Overall, the particle theory is a theory that helps us understand our world better.]]> 2018-01-06 02:18:47 UTC https://padlet.com/826142/uuns7g2cxnlw/wish/219056520
