2. 0/2 points Previous Answers B My Notes A cylinder that has a 39.0-cm radius and is 50.0 cm deep is filled with air at 20.5°C and 1.00 atm as shown in figure (a). The temperature is held constant as a 19.0-kg piston is lowered into the cylinder, compressing the air trapped inside as it takes equilibrium height has in figure (b). Finally, with the temperature sill held to a constant 20.5°C, a 29.5-kg dog stands on the piston, further compressing the air (c). 50.0 cm (a) How far down (An) does the piston move when the dog steps onto it? Your response differs from the correct answer by more than 10%. Double check your calculations. mm (b) To what temperature should the gas be warmed to raise the piston and the dog back to hi?

My Notes The mass of a hot-air balloon and its cargo (not including the air inside) is 160 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is 530 m. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0°C is 1.244 kg/m .) We know from Archimedes' principle that the weight of the displaced air must equal the weight of the balloon plus the weight of the air inside. K Need Help? Read It Master it
