A glass flask whose volume is 1000.0 cm3 at 0.0°C is completely filled with mercury at this temperature. When flask and mercury are warmed to 55.0°C, 8.95 cm3 of mercury overflow. If the coefficient of volume expansion of mercury is 18.0 x 10-5 K1, compute the coefficient of volume expansion of the glass.

A steel rod and a bronze rod are heated. At zero degree Celsius, the steel rod has a Ls  and the bronze rod has a length of Lb. When the rods are heated or cooled, the difference between their length stays constant at 5.00 cm. Determine the values of Ls and Lb.

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

The pipe 8 m long has an inner radius of 70 mm, an outer radius of 80 mm, and is made of stainless steel (k = 15 W / [m ° C]). The inner surface temperature is maintained at 180 ° C, and the outer surface is 30 ° C. At constant conditions and there is no heat generation from the pipe, calculate the heat transfer rate that occurs in the pipe wall. = watts

The mass of a hot-air balloon and its cargo (not including the air inside) is 160 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is 550 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0°C is 1.244 kg/m3.) K=??
