Heat And Temp Flashcards
1
Q
What is Temperature?
A
- Temperature is a measure of the amount of vibration or speed of motion of particles.
- In hot objects, the particles vibrate strongly, while in a cold object, the particles do not vibrate as much.
2
Q
What is Heat?
A
- Heat is the form of energy that is transferred between two substances at different temperatures.
- Heat is transferred from place to place in one of three possible ways: conduction, convection, radiation
3
Q
What is Conduction?
A
- Conduction is the transfer of heat between substances that are in direct contact with each other.
- Metals are good conductors.
- The process involves particles passing vibration from one to the next until the end, like a travel line.
4
Q
What is Convection?
A
- Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
- Cooler particles then take the place of warmer particles.
- This results in a continuous circulation pattern.
5
Q
What is Radiation?
A
- Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object.
- It involves the release of electromagnetic waves.
- Radiation mainly primarily travels inside of a vacuum.
6
Q
What is the Difference between a Conductor and an Insulator?
A
- A conductor is a material that easily transfers energy, usually heat or electricity, from one place to another easily.
- Insulators trap heat in one location and do not allow for energy to move through them.
