A sample of methane gas at a pressure of 0.828 atm and a temperature of 27.0 °C, occupies a volume of 19.4 liters. If the gas is compressed at constant temperature to a volume of 4.35 liters, what will the pressure of the gas sample be?

How would the graph in Figure 9.12 change if the number of moles of gas in the sample used to determine the curve were doubled?

A typical barometric pressure in Redding. California, is about 750 mm Hg. Calculate this pressure in atm and kPa.

Which of the following statements is(are) true? a. If the number of moles of a gas is doubled, the volume will double, assuming the pressure and temperature of the gas remain constant. b. If the temperature of a gas increases from 25C to 50C, the volume of the gas would double, assuming that the pressure and the number of moles of gas remain constant. c. The device that measures atmospheric pressure is called a barometer. d. If the volume of a gas decreases by one half, then the pressure would double, assuming that the number of moles and the temperature of the gas remain constant.
