Question

Which has a higher specific heat, water or sand? Derive the relation between the co- efficient of the linear expansion and superficial expansion.

Answer 1

Answer:

Because water has a high heat capacity, it requires more energy to raise the temperature by one degree. The sun puts out a more or less constant rate of energy, which heats up sand more quickly and water more slowly. Sand has a much lower specific heat than water—that's why it gets hot so fast!

Explanation:

The ratio increase in length original length for 1 degree rise in temperature is called the coefficient of linear expansion, the ratio increase in area original area for 1 degree rise in temperature is called the coefficient of superficial expansion, and the ratio increase in volume original volume for 1 degree rise in
