The initial temperature of three moles of oxygen gas is 23.5°C, and its pressure is 6.30 atm. (a) What will its final temperature be when heated at constant volume so the pressure is two times its initial value? °C (b) Now the volume of the gas is also allowed to change. Determine the final temperature if the gas is heated until the pressure and the volume are quadrupled. °C

4. An ideal gas is contained in a vessel of volume 12 L (12 liters) at a temperature of 20 °C and a pressure of 9 atm. a) How many moles of gas are in the vessel? b) How many molecules of gas are in the vessel?

You have a container of neon (Ne) gas at 290 K. The volume of the container is 0.1 m3 and the pressure is 2.1 atm. a) How many Ne atoms are in the container? b) How many moles of Ne are in the container?

An ideal gas with y = 1.67 is initially at 2°C in a volume of 8 L at a pressure of 1.00 atm. It is then expanded adiabatically to a volume of 8.5 L. What is the final temperature of the gas? -20°C -23°C 2.5°C -8.9°C 68°C

Gas is contained in a 6.00-L vessel at a temperature of 18.0°C and a pressure of 8.00 atm. (a) Determine the number of moles of gas in the vessel. 2.00 mol (b) How many molecules are in the vessel? 1.205 X A mole of objects is equal to how many objects? molecules

On a chilly 10°C day, you quickly take a deep breath—all your lungs can hold, 4.0 L. The air warms to your body temperature of 37°C. If the air starts at a pressure of 1.0 atm, and you hold the volume of your lungs constant (a good approximation) and the number of molecules in your lungs stays constant aswell (also a good approximation), what is the increase in pressure inside your lungs?

One mole of oxygen gas is at a pressure of 5.45 atm and a temperature of 27.5°C. (a) If the gas is heated at constant volume until the pressure triples, what is the final temperature? °C (b) If the gas is heated so that both the pressure and volume are doubled, what is the final temperature? °C Submit Answer

A sealed 99 m3 tank is filled with 6000 moles of ideal oxygen gas (diatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 320 K. The atomic mass of oxygen is 16.0 g/mol. The mass density of the oxygen gas, in Sl units, is closest to:

2.40 moles of an ideal gas is initially at 40.0 oC and 1.35 atm. a) What is its volume under these conditions?b) If it is then compressed to one third of its initial volume and its pressure increases to 2.0 atm, what, in Centigrade degrees, will be its temperature?
