You are looking to buy a small piece of land in Hong Kong. The price is "only"' $60,000 per square meter. The land title says the dimensions ale 20 m 30 m. By how much would the total price change if you measured the parcel with a steel tape measure on a day when the temperature was 20 above the temperature that the tape measure was designed for? The dimensions of the land do not change.
A liquid has a density . (a) Show that the fractional change in density for a change in temperature T is / = T. (b) What does the negative sign signify? (c) Fresh water has a maximum density of 1.000 0 g/cm3 at 4.0C. At 10.0C, its density is 0.999 7 g/cm3. What is for water over this temperature interval? (d) At 0C, the density of water is 0.999 9 g/cm3. What is the value for over the temperature range 0C to 4.00C?
A volumetric flask made of Pyrex is calibrated at 20.0C. It is filled to the 100-mL mark with 35.0C acetone. After the flask is filled, the acetone cools and the flask warms so that the combination of acetone and flask reaches a uniform temperature of 32.0C. The combination is then cooled back to 20.0C. (a) What is the volume of the acetone when it cools to 20.0C? (b) At the temperature of 32.0C, does the level of acetone lie above or below the 100-mL mark on the flask? Explain.
The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0C and 101 kPa. The volume of the balloon is 400 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0C is 1.244 kg/m3.)

An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10.0C. Two metallic blocks are placed into the water. One is a 50.0-g piece of copper at 80.0C. The other has a mass of 70.0 g and is originally at a temperature of 100C. The entire system stabilizes at a final temperature of 20.0C. (a) Determine the specific heat of the unknown sample. (b) Using the data in Table 19.1, can you make a positive identification of the unknown material? Can you identify a possible material? (c) Explain your answers for part (b).
