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
