Specific Heat Capacity

• A substance that is the thermal energy required to change the temperature of 1 kilogram of the substance by 1 C.

• a substance that uses thermal energy to generate heat.

What is the correct equation for Fahrenheit to Celsius?

What is pressure's equation?

Which equation goes with kelvin to celsius?

What is the proper equation for the heat required to change from one phase to another?

what is the equation of coefficient of thermal expansion

• change in lenght= coefficient of thermal * expenension inital lenght * temperature change

• change in lenght= initial lenght * temperature change

• change in length= initial length* coefficient of thermal expesension

• initial lenght = coefficient of thermal energy * temperature change
