A stone floor feels very cold to bare feet in the winter but a carpet in the same room feels comfortably warm. Why?
Occasionally, huge icebergs are found floating on the ocean's currents. Suppose
one such iceberg has a regular volume and is 120 km long, 35 km wide, and
230 m thick.
(1)
How much heat would be required to melt this iceberg (assumed to be at
0°C) into liquid water at 0°C? (The density of ice is 917 kg/m³. The latent
heat of fusion for ice is 33.5x104 J/kg.)
(ii) Assume the average annual energy consumption by a developed country
in the past years was 9.3 x1o19 J. If this energy were delivered to the
iceberg every year, how many years would it take before the ice is
completely melted?
How much heat is absorbed by a persons hand if 100 grams of liquid water at 100°C is poured on his hand? (Assume the final temperature of the water will be normal body temperature of 37°C)
How much heat is absorbed by a persons hand if 100 grams of steam at 100°C is first converted to liquid water at 100°C and then cooled to normal body temperature?
Which causes the more severe burn hot water or steam? Why?
