1. Calculate the initial volume of a gas if it is compressed to a final volume of 1.4 L at a constant pressure of 2.7 atm and results in 457.J of work.
Part 1: Air at 1 atm and 200° C occupies an initial volume Vi of 1000 cm3 in a cylinder. The air is confined by a piston which has a constant restraining force so that the gas pressure remains constant. Heat is added to the air until its temperature reaches 2600° C. Calculate the heat added Calculate the work done by the gas Calculate the change in internal energy of the gas Part 2: An ideal gas is contained in...
A snorkeler with a lung capacity of 5.0 L inhales a lungful of air at the surface, where the pressure is 1.0 atm. The snorkeler then descends to a depth of 43 m , where the pressure increases to 5.3 atm What is the volume of the snorkeler's lungs at this depth? (Assume constant temperature.)
