We have two equal-size boxes, A and B . Each box contains gas that behaves as an ideal gas. We insert a thermometer into each box and find that the gas in box A is at 50°C while the gas in box B is at 10°C. This is all we know about the gas in the boxes. Which of the following statements must be true? Which could be true? Explain your reasoning. (a) The pressure in A is higher than in B . (b) There are more molecules in A than in B . (c) A and B do not contain the same type of gas. (d) The molecules in A have more average kinetic energy per molecule than those in B . (c) The molecules in A are moving faster than those in B .

A 22-cm-diameter vertical cylinder is sealed at the top by a frictionless 16 kg piston. The piston
is 79 cm above the bottom when the gas temperature is 303° C. The air above the piston is at
1.00 atm pressure.
