A spherical balloon containing nitrogen gas has a radius of 38 cm. If the balloon is at atmospheric pressure and room temperature (293 K), find the average spacing between molecules in the balloon. (Assume each molecule takes up the volume of a cube of side length L.)
A 5.7 kg quantity of water is held at constant volume in a pressure cooker and heated with a range element. The systems internal energy increases by 37x10^3 J. But, the pressure cooker is not well insulated, and 6x10^3 J of energy is transferred to t..
