Two objects made of the same material have the same external dimensions and appearance, but one is solid and the other is hollow. When their temperature is increased, is the overall volume expansion the same or different? Why?
Suppose that you cut a small gap in a metal ring. If you were to heat the ring, discuss whether the gap would become wider or narrower.
Which generally expands more for an equal increase in temperature: solids or liquids? Explain.
Freezing a can of soda will cause its bottom and top to bulge so badly the can will not stand up. What has happened?
Why can’t you establish whether you are running a high temperature by touching your own forehead?
A brass telephone wire has essentially no sag between poles 35.0 m apart on a cold day when the temperature is -20.0°C. How much longer is the wire on a summer day when the temperature is 35.0°C? If we change the kind of wire copper, how much longer is it during summer? Which is longer?
One of the tallest buildings in the world has a height of 1671 feet. Assume that this height was measured on a winter day when the temperature was 16°C. You could use the building as a sort of giant thermometer on a hot summer day by carefully measuring its height. Suppose you do this and discover that the building is 0.581 foot taller than its official height. What is the temperature, assuming that the building is in thermal equilibrium with the air and that its entire frame is made of copper?
Gas is confined in a tank at a pressure of 11.0 atm and a temperature of 25.0°C. If two-thirds of the gas is withdrawn and the temperature is raised to 75.0°C, what is the pressure of the gas remaining in the tank?
A rigid tank contains 1.50 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 25.0 atm to 5.00 atm. Assume the volume of the tank and the temperature of the gas remain constant during this operation.
