What is internal energy? If you had a gram of copper
and a gram of water, both at temperature 0° C, would
they have the same internal energy?
What is temperature? When two objects have the
same temperature, what physically is the same
What is specific heat?Why is the specific heat
of water so much larger than that of copper?
What is meant by a phase change? Since large
energies are required to change the phase, why
doesn't the temperature change?
What is heat? Does an object contain a measureable
property called heat?
What are the common means of transferring heat
from a hot object? What cooling mechanisms are
used by the human body?
Is there any way to get heat to move from a cold
object to a hot object?
What is meant by the Greenhouse effect?
How does radiation explain phenomena like a
red hot poker? the 3K background radiation?
If a uniform metal plate with a hole in it is
heated, will the hole get larger or smaller?
If the pressure on a constant temperature
gas is doubled, what will happen to its
If the temperature of a constant volume of
gas is doubled, what will happen to the
Why must absolute temperature and absolute
pressure be used in calculating the final
volume and temperature in the above examples?
What is a heat engine?
What is the First Law of Thermodynamics?
What limits are placed on heat engines by
the First Law of Thermodynamics?
What is the Second Law of Thermodynamics?
What additional limits are placed on heat engines
by the Second Law of Thermodynamics?
Suppose the state legislature passed a law requiring all electric power plants to operate at at least 75% efficiency. Could it be done?
Is there any way to get heat to move from a cold object to a hot object?
