A sample of ideal gas havingfdegrees of freedom and containingnmoles are confined to a cylinder with a frictionless piston. The pressure in and out of the cylinder are equal. However, the temperature ofthe gas inside the cylinder is To while the outside is a heat reservoir at temperature TH, assumed greater than To. As the gas inside the cylinder absorbs heat from the outside it begins an isobaric expansionuntil its temperature reaches TH. Required:
Determine an expression for the heat transferred to the gas from the heat reservoir in terms of f, n, T., To, and the gas constant R.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
