a cylinder with a radius of 40cm and a depth of 50cm is filled with air at a temperature of 20°c and a pressure of 1.0atm, as shown in figure (a). the piston has a final mass. until equilibrium at height h as in figure (b). 25.0kg stood on the piston to blow air with a temperature of 20.0°c as shown (c). a. how much does the piston move down when the dog is standing on it? b. what is the air temperature equal to the piston and the dog up to height hi?
