During a long sleepless night, you wonder about the thermodynamic properties of the air in your room. If your room has a volume of 20 m3, the pressure is 9.8x 104 Pa and the temperature is 20°C, what is the total translational kinetic energy of the air molecules in your room?

A canister with a piston contains 1.05 kg of air at 30.0°C and 1.25 x 105 Pa. Energy is transferred by heat into the system as it expands and the pressure rises to 4.25 x 105 Pa. Throughout the expansion, the relationship between pressure and volume is given by P = cv1/2) where C is a constant. Air may be modeled as a diatomic ideal gas with a molar mass of M = 28.9 g/mol. Determine the following. (a) initial volume (in m3) 0.01477 The ideal gas law may be used to describe the air in any state, Since we want the initial volume, we should use the pressure and temperature for the initial state. How can you determine the number of moles of air from the total mass and the molar mass? m3 (b) final volume (in m) m3 (c) final temperature (in K) K (d) work done on the air (in J) (e) energy transferred by heat (Enter the magnitude in MJ.) MJ

An ideal gas is heated at a constant pressure of 1.80 x 10 Pa from a temperature of -73.0°C to a temperature of +27.0°C. The initial volume of the gas is 0.100 m³. The heat energy supplied to the gas in this process is 40.0 kJ. What is the increase in internal energy of the gas? -8.95:kJ

During a long sleepless night, you wonder about the thermodynamic properties of the air in your room. If your room has a volume of 24 m3, the pressure is 9.9x 104 Pa and the temperature is 20°C, what is the total translational kinetic energy of the air molecules in your room?
