A lab rat lifts a 200 g mass 1.55 m high as it spins on a Ferris wheel. At the same time, it loses 5.0 J of energy as heat. What would be the internal energy change if the animal was thought of as a closed system, ignoring all other losses? note:Assume that all gases are ideal gases unless otherwise stated. All thermochemical data are for 298.15 K.

A monatomic ideal gas initially fills a V0 = 0.35 m3 container at P0 = 75 kPa. The gas undergoes an isobaric expansion to V1 = 1.5 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compression to its initial pressure and volume. 1. Calculate the heat absorbed Q2, in kilojoules, during the isovolumetric cooling (second process).  2. Calculate the change in internal energy by the gas, ΔU2, in kilojoules, during the isovolumetric cooling (second process).  3. Calculate the work done by the gas, W3, in kilojoules, during the isothermal compression (third process).  4. Calculate the change in internal energy, ΔU3, in kilojoules, during the isothermal compression (third process).  5. Calculate the heat absorbed Q3, in kilojoules, during the isothermal compressions (third process).

A car tire contains 0.0390 m3 of air at a pressure of 2.20×105 N/m2 (about 32 psi). How much more internal energy does this gas have than the same volume has at zero gauge pressure (which is equivalent to normal atmospheric pressure)?

A gas contained in a cylinder fitted with a frictionless piston expands against a constant external pressure of 1atm from a volume of 5L to a volume of 10L. In doing so, it absorbs 400 J of thermal energy from its surroundings. Determine the change in internal energy of system.

A 1 mol sample of a diatomic ideal gas (γ=1.4) expands slowly and adiabatically from a pressure of 18 atm and a volume of 3 L to a final volume of 18 L. What is the final temprature (in K) of the gas? ( Answer no decimal )

Question B: A sample of 1.00 mole of a diatomic ideal gas is initially at temperature 265 K and volume 0.200 m3. The gas first undergoes an isobaric expansion, such that its temperature increases by 110.0 K. It then undergoes an adiabatic expansion so that its final volume is 0,440 m3. i. Sketch a PV diagram for the two-step process, including labeled initial, final, and intermediate states, and a two-part curve/path with an arrow indicating direction.
