It’s possible to boil water by adding hot rocks to it, a technique that has been used in many societies over time. If you heat a rock in the fire, you can easily get it to a temperature of 500°C. If you use granite or other similar stones, the specific heat is about 800 J/kg ⋅ K. If 5.0 kg of water at 10°C is in a leak-proof vessel, what minimum number of 1.0 kg stones must be added to bring the water to a boil?

The height of the Washington Monument is measured to be 170 m on a day when its temperature is 35.0°C. What will the change in its height be on a day when its temperature falls to -4.5°C? Although the monument is made of limestone, take the thermal coefficient of expansion to be the same as for marble, which is 2.50 x 10-6/°C. (Be sure to include the appropriate sign with your answer.). Enter a number. length and temperature are always defined as final value minus the initial value. Therefore be sure to consider the cign quantities om
