Hi kim, you told that you missed the class about states of matter. can i explain you?
Alright, let me explain to you as much as I can......
Particle theory states that matter is made up of small particles which are constantly moving. Particle theory categorize the three main states of matter that we see every day – solid, liquid, and gas
Particle Theory of Matter - 1. All Matter is made up of particles 2. all particles are in constant motion 3. all particles of one substance are identical 4.temperature affects the speed at which particles move 5. in a gas, there are spaces between the particles 6. in liquids and solids, the particles are close together and have strong forces of attraction between them
Sure ......here are few examples of various types of energy being converted into thermal energy which is nothing but heat
Very interesting.......please give more examples for the ways which heat is produced
1. Bouncing a ball where mechanical energy is converted into thermal energy. When the ball hits the ground, some energy of the ball's motion is converted into heat, causing it to slow down at each bounce.
2. Light from the sun is converted to heat as the sun's rays warm the earth's surface.
3. Electrical energy is converted into thermal energy when objects such as heating pads, electrical stove elements, toasters, hair dryers, or light bulbs are used
4. Thermal energy will be transferred to other objects causing them to heat up. When you heat up vessel of water, the heat from the stove causes the molecules in the pan to vibrate faster causing the pan to heat up. The heat from the pan causes water molecules to move faster and heat up. So, when you heat something up, you are just making its molecules move faster.
