Chapter 17 Flashcards
1
Q
specific heat
A
energy required to raise the temperature of a unit of mass by 1 degree
2
Q
heat capacity
A
the ability of a material to absorb heat
3
Q
Heat capacity increases with temperature. (T or F)
A
True
4
Q
thermal conductivity
A
the ability of a material to transport heat
5
Q
atomic perspective
A
atomic vibrations and free electrons in hotter regions transport energy to cooler regions
6
Q
What causes thermal stresses? (2)
A
-restrained thermal expansion/ contraction
-temperature gradients that lead to differential dimensional changes
7
Q
thermal shock
A
stress due to nonuniform heating/ cooling causes failure
