- 1. You are looking to purchase a small piece of land in Hong Kong. The price is "only" $ 62000 per square meter! The land title says the dimensions are 21 m x 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 °C above normal? The coefficient of linear exapansion of steel is a = 1.2x10-5/°C. The price by $ increases decreases15.1. A quartz cube has sides equal to 18.0 cm. What will be its change in volume if its temperature is increased by 275 °F? (the coefficient of volume expansion of quartz is 1.50 × 10–0 °c•1) cm3 ssf60 160 ssf
- 12. At 20°C, an aluminum (αAI = 24.0 x 106 °C-¹) ring has an inner diameter of 5.0000 cm and a brass (αBr = 19.0 x 10-6 °C-¹) rod has diameter of 5.0500 cm. a) If only the ring is heated, what temperature must it reach so that it will just slip over the rod? [437°C] b) What if? If both are heated together, what temperature must they both reach so that the ring just slips over the rod? Would this latter process work? Why? [2100°C, but this will not work because aluminum melts at 660°C]2. An iron ring is to fit snugly on a cylindrical iron rod. At 20 C, the diameter of the rod is 6.445 cm and the inside diameter of the ring is 6.420 cm. To slip over the rod, the ring must be slightly larger than the rod diameter by about 0.008 cm. To what temperature must the ring be brought if its hole is to be large enough so it will slip over the rod?3. A glass flask whose volume is 1000.00 cm³ at 0.0°C is completely filled with mercury at this temper- ature. When the flask and the 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 105 K-1, what is the coefficient of expansion of the glass?
