CP A light, plastic sphere with mass m = 9.00 g and density ρ = 4.00 kg/m3 is suspended in air by thread of negligible mass. (a) What is the tension T in the thread if the air is at 5.00°C and p = 1.00 atm? The molar mass of air is 28.8 g/mol. (b) How much does the tension in the thread change if the temperature of the gas is increased to 35.0°C? Ignore the change in volume of the plastic sphere when the temperature is changed.

A 20.0-kg piston is now lowered into the cylinder, compressing the air trapped inside as it takes equilibrium height hi (Fig. P16.74b).

The cross sectional area of the launch tube is 1.0 cm2, and the length that the projectile travels down the tube after starting from rest is 52 cm. As the gas expands, the pressure varies as shown in Figure P12.4b.
