I'm not understanding c. Can someone explain please? a) In the deep space between galaxies, the density of atoms is as low as 106 atoms/m3, and the temperature is a frigid 2.7 K. What is the pressure (in Pa)? 3.72e-17 b) What volume (in m3) is occupied by 5 mol of gas? 3.01e18 c) If this volume is a cube, what is the length of its sides in kilometers?
(1) An ideal monatomic gas expands isothermally from 0.600 m3 to 1.25 m3 at a constant temperature of 640 K. If the initial pressure is 1.01 ✕ 105 Pa find the following. (a) the work done on the gas J (b) the thermal energy transfer Q J (c) the change in the internal energy J (2) Gas in a container is at a pressure of 1.2 atm and a volume of 5.0 m3. (a) What is the work done on...

A large cylindrical tank contains 0.760 m3 of nitrogen gas at 30.0 ∘C and 1.50×105 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.470 m3 and the temperature is increased to 151 ∘C?
4. A rigid container of 0.2 m3 volume contains a gas at a pressure of 2 bar and a temperature. 25 C. If the characteristic constant for the gas is 0.35 kJ kg-1K-1, calculate: (a) The mass of the gas (b) The pressure of the gas after it is heated to 250°C

A large cylindrical tank contains 0.850 m3 of nitrogen gas at 28.0 ∘C and 8.50×103 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be change What will be the pressure if the volume is decreased to 0.450m ^3 and the temperature is increased to 165 C?
A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas....
A young male adult takes in about 5.80 x 10-4 m3 of fresh air during a normal breath. Fresh air contains approximately 21% oxygen. Assuming that the pressure in the lungs is 1.03 x 105 Pa and air is an ideal gas at a temperature of 310 K, find the number of oxygen molecules in a normal breath.
