An aluminum sphere is 8.90 cm c m in diameter. Part A What will be its % change in volume if it is heated from 30∘C ∘ C to 165 ∘C ∘ C ? The coefficient of volume expansion of aluminium is 75 ×10−6 ∘C-1

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

How would you place two electrons on a sphere of radius r so that the electrostatic potential energy is minimized. how would you place three electrons to solve the same problem.
