Frank has a sample of steel that weighs 80 grams. if the density of his sample of steel is 8 g/cm3, what is the sample’s volume?

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.

The energy produced as a result of this flow of electrons from atom to atom is called
