Determine the amount of work (in J) done on an ideal gas as it is heated in an enclosed, thermally isolated cylinder topped with a freely moving piston. The cylinder contains 0.240 mol of the gas and the temperature is raised from 15.0°C to 270°C. The piston has a mass of 8,300 g and an area of 5.50 cm2.

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
