Helium gas with a volume of 3.20 L, under a pressure of 0.180 atm and at 41.0C, is warmed until both pressure and volume are doubled. (a) What is the final temperature? (b) How many grams of helium are there? The molar mass of helium is 4.00 g/mol.

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 sealed 73 m tank is filled with 8000 moles of ideal oxygen gas (diatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 390 K. The atomic mass of oxygen is 16.0 g/mol. The mass density of the oxygen gas, in Sl units, is closest to: O 7.0 O 4.4 O 2.6 О 35 O 1.8

A hollow container is filled with an ideal gas. The container is designed to maintain a constant pressure by allowing gas to enter or leave as needed. at all times the gas and container are in thermal equilibrium. initially the temperature is 1078 K. then the temperature decreases to 200 K and the volume decreases to .88 times the initial volume. determine the coefficient of volume expansion for the container and the ratio of the final number of moles to the initial number of moles. Please include the units, and round to the fourth decimal point.

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 25.0% of its original volume and the temperature is increased to 35.0°C. (a) What is the pressure in the tire (absolute)? Pa (b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 2.00%. What is the new pressure in the tire (absolute)? Pa

The initial temperature of three moles of oxygen gas is 33.5°C, and its pressure is 7.80 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 doubled. °C

(a) How many molecules are present in a sample of an ideal gas that occupies a volume of 1.90 cm³, is at a temperature of 20°C, and is at atmospheric pressure? molecules -11 (b) How many molecules of the gas are present if the volume and temperature are the same as in part (a), but the pressure is now 1.50 x 10¯ Pa (an extremely good vacuum)? molecules

The density of helium gas at 0.0◦C is0.16 kg/m3kg/m3. The temperature is thenraised to 102 ◦C, but the pressure is kept constant.Assuming that helium is an ideal gas, calculate the new density of the gas.Answer in units of kg/m3.

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?
