A cube of solid aluminum (beta=0.000072 per Kelvin) has a volume of 1.00 m^3 at 20 degrees Celsius. What temperature change is required to produce a 100-cm^3 increase in the volume of the cube?

At 20∘C, the hole in an aluminum ring is 2.400 cm in diameter. You need to slip this ring over a steel shaft that has a room-temperature diameter of 2.406 cm. 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 and 23×10^-6 K^-1 respectively. Express your answer in degrees Celsius to two significant figures.

A sealed 73 m tank is filled with 8000 moles of ideal oxygen gas (diatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 390 K. The atomic mass of oxygen is 16.0 g/mol. The mass density of the oxygen gas, in Sl units, is closest to: O 7.0 O 4.4 O 2.6 О 35 O 1.8

How many grams of coffee must evaporate from 700 g of coffee in a 190 g glass cup to cool the coffee and the cup from 95.0°C to 24.0°C? Assume the coffee has the same thermal properties as water and that the average heat of vaporization is 2,340 kJ/kg (560 cal/g). Neglect heat losses through processes other than evaporation, as well as the change in mass of the coffee as it cools. g Do the latter two assumptions cause your answer to be higher or lower than the true answer? O My answer is lower than the true answer because, if coffee loses heat in other ways and its mass decreases, it will need more evaporation for the same temperature drop. O My answer is higher than the true answer because, if coffee loses heat in other ways and its mass decreases, it will need less evaporation for the same temperature drop. O My answer is higher than the true answer because, if coffee loses heat in other ways and its mass decreases, it will need more evaporation for the same temperature drop. O My…
