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.

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.
