- Three moles of an ideal monatomic gas are at a temperature of 381 K. Then 2959 J of heat is added to the gas, and 651 J of work is done on it. What is the final temperature of the gas? Number Units the tolerance is +/-2%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.) MJAn 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.
