Cecily is inflating her bicycle tyre with the pump below. When she pushes the plunger down, it is doing work against the air inside the plunger and so it is transferring energy to the air particles. As a result, the temperature of the air will... what?

8. A bicycle pump contains 70 cm3 of air at a pressure of 1.0 atmosphere and a temperature of 7°C. Whenthe air is compressed to 30 cm3 the temperature rises to 27 °C.This is because the person is doing work on the gas inside thepump, which increases the internal energy of the gas. Themolecules move faster and the temperature rises. What is thepressure now?Ans:

How would increasing temperature of the compressed air affect the pressure in the can, explain your answer

A cylinder is filled with a gas and then sealed, so that the gas has a fixed volume. The gas molecules are given energy so that their average speed increases. What happens to the pressure and to the temperature of the gas in the cylinder?

Marc attaches a falling 500-kg object with a rope through apulley to a paddle wheel shaft. He places the system in a well-insulated tank holding 25 kg of water. When the object falls, itcauses the paddle wheel to rotate and churn the water. If theobject falls a vertical distance of 100 m at constant speed, what isthe temperature change of the water? (1 kcal = 4 186 J, thespecific heat of water is 4 186 J/kg C, and g = 9.8 m/s2).A-19600℃B-4700℃C-4.7℃D-0.8℃

A truck tire is inflated on a cold morning. Throughout the day, the tire heats up due to rising outdoor temperatures and friction with the road. Will the pressure inside the tire increase or decrease?
