An ice chest at a beach party contains 12 cans of soda at 2.15 °C. Each can of soda has a mass of 0.35 kg and a specific heat capacity of 3800 J/(kg C°). Someone adds a 8.60-kg watermelon at 26.3 °C to the chest. The specific heat capacity of watermelon is nearly the same as that of water. Ignore the specific heat capacity of the chest and determine the final temperature T of the soda and watermelon in degrees...

A vertical cylinder contains N atoms of an ideal gas and is closed off by a piston having mass m and area a. The acceleration due to gravity is g. The gas has a heat capacity Cy which is independent of temperature. (Note that the preceding sentence contains the words "heat capacity" and does not contain the words "specific heat.") Neglect the heat capacity of the cylinder and piston, ignore friction, and the entire system is thermally insulated. The piston...

Problem 5- A piston-cylinder device initially contains steam at 3.5 MPa, superheated by .10°C. Now, steam loses heat to the surroundings and the piston moves down, hitting a set of stops, at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at .200C. Determine the initial temperature of the steam a. b.
