One mole of oxygen gas is at a pressure of 6.85 atm and a temperature of 31.0°C. (a) If the gas is heated at constant volume until the pressure triples, what is the final temperature? (b) If the gas is heated so that both the pressure and volume are doubled, what is the final temperature?

The most probable speed for molecules of a gas at 296 K is 263 m/s. What is the molar mass of the gas? (You might like to figure out what the gas is likely to be.)

The pressure in a constant-volume gas thermometer is 0.700 atm at 100°C and 0.512 atm at 0°C. (a) What is the temperature when the pressure is 0.040 0 atm? (b) What is the pressure at 450°C?

You are inflating the tires on your bicycle using a manual pump. The volume inside of the pump is initially 0.16 m cube with a pressure of 2 atm. If you push down on the piston and reduce the volume inside to 0.07 m cube, what is the new pressure inside of the pump? Assume the temperature inside the pump stays constant.

Problem 7: Hydrogen molecules, with a molar mass of 2.016 g/mol, in a certain gas have an rms speed of 345 m/s. What is the temperature of this gas, in kelvins? T=

A tank contains one mole of nitrogen gas at a pressure of 5.20 atm and a temperature of 24.5°C. The tank (which has a fixed volume) is heated until the pressure inside triples. What is the final temperature of the gas?  °C (b)A cylinder with a moveable piston contains one mole of nitrogen, again at a pressure of 5.20 atm and a temperature of 24.5°C. Now, the cylinder is heated so that both the pressure inside and the volume of the cylinder double. What is the final temperature of the gas?  °C

A 7.00-L vessel contains 3.50 moles of gas at a pressure of 1.60 × 106 Pa. Find (a) the temperature of the gas and (b) the average kinetic energy of the gas molecules in the vessel. (c) What additional information would you need if you were asked to find the average speed of the gas molecules?

The density of helium gas at 0°C is po = 0.179 kg/m³. The temperature is then raised to T = 160°C, but the pressure is kept constant. Assuming that helium is an ideal gas, calculate the new density p, of the gas. kg/m³

(a) 0.3740 moles of krypton gas is placed in a 9.75 L container at 239 K. Find the pressure of the gas in bar? (b) What is the average kinetic energy per mole of krypton gas atoms featured in the previous part? Report your answer in J/mol.

Two glass containers, of equal volume each hold a mole of gas. Container 1 is filled with hydrogen gas (molar mass 2 g / mol), and Container 2 holds helium (molar mass 4 g / mol). If the pressure of the gas in Container 1 equals the pressure of the gas in Container 2, which of the following is true?   (a)  The temperature of the gas in Container 1 is lower than the temperature of the gas in Container 2. (b)  The temperature of the gas in Container 1 is greater than the temperature of the gas in Container 2. (c)  The value of R for the gas in Container 1 is ½ the value of R for the gas in Container 2. (d)  The rms speed of the gas molecules in Container 1 is lower than the rms speed of the gas molecules in Container 2. (e)  The rms speed of the gas molecules in Container 1 is greater than the rms speed of the gas molecules in Container 2.
