There are 5 main points of the particle theory and they are:
1. All matter is made up of tiny particles
2. Particles have empty spaces between them
3. Particles are moving randomly all the time
4. Particles move faster and spread apart when heated
5. Particles attract each other, so they stay together instead of flying apart.]]> 2017-12-19 20:03:48 UTC https://padlet.com/8172181/hh2cx5czjala/wish/217364761 8172181 https://padlet.com/8172181/hh2cx5czjala/wish/218640203 Heat can be produced in different ways. Some ways are: 
-Burning (creating a fire)
-Friction/rubbing 
-Electricity
-Sun
-Chemical energy
-Thermal energy

The sun and creating a fire are natural ways of how heat is produced.
You can rub your hands and as you do, you'll feel heat between them and that is an example of friction/rubbing something together.
The food we eat is chemical energy and when it does enter our body, it produces heat.
When your boiling water, the heat from the stove creates thermal energy.
Electricity wires could heat up using its thermal energy

An example is starting with ice. When heat is applied to the ice, its particles would start to expand and eventually, it would turn into a liquid. If you continue to add heat to the liquid, the particles would spread out further and turn into a gas but because the particles are not as close as they were before, they are not as strong which is why they are a gas. This method is burning. The heat makes the particles move faster and makes the particles expand  changing them into different states. These particles are tiny and they do have spaces between them because for example, if you move a bowl of water around, you will see the water moving. If the particles did not attract each other, an objects particles would not be stable.]]> 2018-01-04 21:11:18 UTC https://padlet.com/8172181/hh2cx5czjala/wish/218855965 8172181 https://padlet.com/8172181/hh2cx5czjala/wish/219568036 2018-01-08 22:03:09 UTC https://padlet.com/8172181/hh2cx5czjala/wish/219568036 8172181 https://padlet.com/8172181/hh2cx5czjala/wish/219568616 Not only does heat effect the particles of an object but it affects the volume as well. When a solid changes into a liquid, the volume stays the the same. When a liquid changes into a gas, the volume changes because gas can be compressed.]]> 2018-01-08 22:05:53 UTC https://padlet.com/8172181/hh2cx5czjala/wish/219568616
