A tank of coefficient of volume expansion 6.0 x10^-5/C filled with 2.0 m^3 of a liquid of coefficient of volume 18 x 10^-5/C is at a temperature of 40 degrees C and is in thermal equilibrium. The tank and liquid is cooled to 20 degrees C. How much more liquid can be added to the tank? 6. In an immersion measurement of a woman's density, she is found to have a mass of 60.0 kg in air and an apparent mass of 0.090 kg when completely submerged with lungs empty. (a) What is her volume? 7. A rod made of two materials: one of length 2.0 m and thermal conductivity of 385 W/m K and the other of length L and thermal conductivity of 35 W/m K. Both have an cross sectional area of 5.00 cm^2. The temperature at the junction between the two materials is 70 degree C. If the temperature of the far end of the 2 cm length material is 100 degrees C and the temperature of the far end of the L length material is 0 degrees C how much heat per second flow from the far side of the 2 m material to the far side of the L length material and what is L? 8. If the temperature of 2.0 moles of a gas with a heat capacity of 12.5 J/kg C is increased by 40 K. How much heat was added to the gas? 9. A gas undergoes isobaric expansion and 600 J of work is done by the gas. The gas pressure is 1 atm and volume is 22 L. What is the amount of heat the gas absorbs if it's thermal energy is increased by 90 J? 10. A container of water has a cross-sectional area of 0.1m, A piston sits on top of the water. There is a spout located 0.15 m from the bottom of the tank, open to the atmosphere, and a stream of water exits the spout. The cross sectional area of the spout is 7 x 104 m. (a) What is the velocity of the water as it leaves the spout?
