Thermodynamics Ch.17 Flashcards
1
Q
spontaneous
A
a process that occurs without outside intervention
2
Q
non-spontaneous
A
a process that only occurs only as long as energy is continued to be added to the system (is the reverse process)
3
Q
first law of thermodynamics
A
energy cannot be created or destroyed
4
Q
second law of thermodynamics
A
not all of the energy released by a spontaneous reaction
5
Q
Gas –> Liquid –> solid
A
energy out
6
Q
solid–> liquid–>gas
A
energy in
7
Q
what happens to the heat capacity of a material if its mass is doubled?
A
the heat capacity would increase because heat capacity is inversely proportional to mass
8
Q
what happens tot eh specific heat of a material if it mass is doubled
A
there is no change, specific heat is an intensive property of a material, independent of the amount
9
Q
A
