Changes in Internal Energy
Physics: Cambridge International GCSE Supplement, topic 2.2.2
Changes in Internal Energy
We calculate the change in internal energy by multiplying together an object's mass, its specific heat capacity and the change in temperature.
Object's mass
Specific heat capacity
Change in temperature
Test yourself on Changes in Internal Energy
If the change in internal energy = 100J, mass = 10kg, and temperature change = 1°C, what is the specific heat capacity?
Which units are used to measure the change in an object's internal energy?
State the difference between thermal capacity and specific heat capacity.
