Acylinder with a moveable piston contains 92g of nitrogen. the external pressure is constant at 1.00 atm. the initial temperature is 200k. when the temperature is decreased by 70 k, by putting it in a lower temperature freezer, the volume will decrease, according to the ideal gas law. calculate the work for this process.

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. the temperature at the start of the reaction was 23.0°c and at the end it was 19.0°c. calculate the energy absorbed by the reaction.

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?
