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

m = 0.593 kg of methanol in atmospheric pressure is heated with an electric heater from T₁ = 30.2 °C to its boiling point. After the heating my methanol is vaporized. Heating and vaporizing takes t = 450.41 s with n=0.59 heater's efficiency. What is the volume of methanol? V = What is the energy required for heating? E₁ = 1 kJ m³ Your last answer was interpreted as follows: 1 What is the energy required for vaporizing? Ev = 1 kJ Your last answer was interpreted as follows: 1 What is the power of the heater? P = 1 с Your last answer was interpreted as follows: 1 Your last answer was interpreted as follows: 1 What is the electr. energy needed for heating and vaporizing?
