Temperature Test Review

Temperature

Temperature is the measure of the average kinetic energy of the particles.

1. ​the more kinetic energy (faster the molecules are going) the higher the temperature.

2. the less kinetic energy (slower the ​molecules are going) the lower the temperature

Water

when does water change?

Boiling point:

100C 212F 373 K

freezing point:​

0C 32F 272K​

Some text here about the topic of discussion

K=C+273

C=K-273

F= 1.8xC +32

C= (F-32) 5/9​

What transfers heat??

Some text here about the topic of discussion

Heat

Heat is the transfer of thermal energy. thermal energy can be transferred in three different ways.

Some text here about the topic of discussion

Heat transfer

​Radiation

1. ​Heat transfer through electromagnetic waves

2. can travel through a vacuum

3. does not need particles to travel

4. the hotter it is the more it radiates out​

​

heat transfer

Convection

1. heat transfer through fluids

2. hot fluids rise

3. hot fluids expand​

​

heat transfer

Conduction

1. ​Heat transfer through solids

2. objects must be touching

3. heat travels from hot to cold ​
