A system gains 1680 J of heat, while the internal energy of the system increases by 6020 J and the volume decreases by 0.0121 m3. Assume the pressure is constant and find its value. number                    units

A sample of gas is compressed to one-third of its initial volume at a constant pressure of 1.25 × 105 Pa. During the compression 100J of work is done on the gas. What is the final volume of the gas?

A gas contained in a cylinder fitted with a frictionless piston expands against a constant external pressure of 1atm from a volume of 5L to a volume of 10L. In doing so, it absorbs 400 J of thermal energy from its surroundings. Determine the change in internal energy of system.

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?
