Q. Suppose a bar 2 m long expands 0.6 cm when heated. By how much will a bar 100 m long of the same material expand when similarly heated?
The specific heat capacity of copper is 0.092 calories per gram per degree Celsius. How much heat is required to raise the temperature of a 10 g piece of copper from 0°C to 90°C?
How much heat is needed to raise the temperature of the same mass of water through the same temperature difference?
Radioactive decay of granite and other rocks in the Earth's interior provides enough energy to keep the interior molten, heat lava, and provide warmth to natural hot springs. This is due to the average release of about 0.03 J per kilogram each year. How many years are required for a chunk of thermally insulated granite to increase 405°C in temperature (assume the specific heat of granite is 800 J/kg °C)?
