A
It measures how hot something is. The unit of measurement is degrees Celsius and sometimes in degrees Fahrenheit. Heat is a form of energy and is measured in Joules, J.
2
Q
What is the formula for working out the total amount of energy used to make the temperature rise?
A
Total Energy Supplied = Energy Supplied Per Second x Number Of Seconds
3
Q
How do you find the amount of energy required to raise the temperature of an object by a certain amount?
A
Energy (J) = Mass (kg) x Specific Heat Capacity (J/kg/Degrees C) x Temperature Change (Degrees C)
4
Q
How do you work out the energy required to boil or melt a certain mass of a material?
A
Energy (J) = Mass (kg) x Specific Latent Heat (J/kg)
