A) At 100C mercury has a specific weight of 130.4 kN/m 3.What volume of the mercury would weigh 2.25 kN?

A 50 L steel tank full of gasoline at -20 C. What is the volume difference for both tank and fuel at 40C. What is the overflow?

A large room contains a volume of air of Va = 15 m3 at a temperature of Ta = 53° F. It also contains a bathtub holding a volume of water of Vw = 0.56 m3 at a temperature of Tw = 101° F.   If the density of the air at Ta is ρa = 1.25 kg/m3, calculate the mass of air in the room in kilograms.  If the density of the water at Tw is ρw = 1000 kg/m3, calculate the mass of the water in the bathtub in kilograms.  Take the room and water as an isolated system. Write an equation for the equilibrium temperature of the system T in terms of ma, Ta, mw, Tw, and the specific heat capacity of the air ca and the water cw.

The gauge pressure in your car tires is 2.55 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska. What is the gauge pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.
