If you seal a container of air at room temperature (20 and then put it in the refrigerator (2 °C), how much will the pressure of the air in the container change? (Remember to convert to Kelvin! Use a ratio so you can simplify...) 1-2b. When you ride a bicycle, your foot pushes down on a pedal that's 17.5 cm (0.175 m) from the axis of rotation. Your force produces a torque on the crank attached to the pedal. Suppose that you weigh 700 N. If you put all your weight on the pedal while it's directly in front of the crank's axis of rotation, what torque do you exert on the crank? (This is really easy -you should get an answer of 122.5 N.m.)
