Thermal Physics Flashcards
1
Q
Define internal energy
A
Sum of potential and kinetic energy in the particles
2
Q
Define expansion in solids
A
Cold solid -> Hot solid
3
Q
What are some examples of the consequences of thermal expansion?
A
Railway lines buckle
Cement paths and buildings crack unless there are expansion joints
4
Q
Define specific heat capacity
A
Energy required per unit mass per unit temperature
5
Q
What is the formula for specific heat capacity?
A
Change in energy = mass x specific heat capacity x change in temperature
Q = m c T
