Physics Chapter 24
When a volume of air compresses and no heat enters or leaves, the air temperature will
increase
Chinook winds tend to
warm an environment
One hundred joules of heat is added to a system that performs 60 joules of work. The internal energy change of the system is
40 J
As a system becomes more disordered, entropy decreases
False
It is possible to wholly convert a given amount of heat energy into mechanical energy
False
The lowest temperature possible in nature is 4 degrees K
False
If a volume of air has a temperature of 0 degrees Celsius, an equal volume of air that is twice as hot has a temperature of about 273 degrees Celsius
True
It is possible to totally convert a given amount of mechanical energy into heat
True
When a volume of air expands against the environment and no heat enters or leaves, the air temperature will
decrease
Suppose you put a closed, sealed can of air on a hot stove burner. The contained air will undergo an increase in
all of these
The first law of thermodynamics is a restatement of the
conservation of energy
The greater the difference in temperature between the input reservoir and output reservoir for a heat engine, the
greater the efficiency
An adiabatic process is characterized by the absence of
heat exchange
