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
about them?
What is heat? Does an object contain a measureable
property called heat?
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?
How is the heat of fusion of ice measured?
What will be the effect on the measured value
if the ice is wet?
What is the First Law of Thermodynamics and
how is it related to conservation of energy?
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?
How does radiation explain phenomena like a
red hot poker? the 3K background radiation?
How can the large energies involved in phase
changes be used to advantage?
What determines the rate at which heat is radiated
from an object?
What is the greenhouse effect? What contributes
to the atmospheric greenhouse effect?
Describe the nature of radiated energy as a
function of the temperature of the radiating object.
If a uniform metal plate with a hole in it is
heated, will the hole get larger or smaller?
What is the difference between evaporation
and boiling?
What is the definition of the boiling point?
How does it change with pressure?
How do you predict the effects on a gas of
changes in pressure, volume, and temperature?
If the pressure on a constant temperature
gas is doubled, what will happen to its
volume?
If the temperature of a constant volume of
gas is doubled, what will happen to the
pressure?
Why must absolute temperature and absolute
pressure be used in calculating the final
volume and temperature in the above examples?
