A canister filled with 3.5 mol of single-atom helium gas has a temperature of 300 K. What is the approximate total internal energy of the gas? (Recall that
3
the equation for kinetic energy due to translation in a gas is: nRT; the
2
equation for kinetic energy due to rotation of a molecule in a gas is: nRT; and
R = 8.31 J/(mol-K).)

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
