Thermal Energy
What is it and how do we measure it?

2. Thermal Energy It is Heat Transferred from one substance to another
Determined by measuring the change in temperature of a substance
Can be found using a known mass of water as an absorber

3. Measuring Heat is measured using the unit- calorie
calorie- amount of heat needed to raise the mass of 1 gram of water by 1ºC
Different than food calorie
Kilocalorie is the food Calorie and is 1,000 calories or the amount of heat needed to raise 1kg or water by 1ºC
It is written as Calorie with a capital C

4. Calculating Thermal Energy
What you Need to Have
Mass
Change in Temperature
Specific Heat of Substance

5. Specific Heat
Some substances take more energy than others to change temperatures
They have a higher specific heat
Specific Heat is the capacity for storing energy
It is different for each substance
For water it is high- 1cal/gºC

6. q = m x c x T q= thermal energy or heat in calories m= mass in grams
c= specific heat in calories divided by (grams x degrees celcius)
T= change in temperature, which is the difference between your ending and beginning temperature
