Alead object and a quartz object each have the same initial volume. the volume of each increases by the same amount, because the temperature increases. if the temperature of the lead object increases by 4.1 °c, by how much does the temperature of the quartz object increase?

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.
