The air temperature above coastal areas ...

The air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when `1m^3` of water cools by `1^@C` will raise the temperature of a much larger volume of air by `1^@C`. Find this volume of air. The specific heat of air is approximately `1 kJ//kg^@C`. Take the density of air to be `1.3 kg//m^3`.

To solve the problem, we need to find the volume of air that can be heated by 1 °C when 1 m³ of water cools by 1 °C. We will follow these steps: ### Step 1: Calculate the mass of 1 m³ of water The density of water is approximately \( \rho_{water} = 1000 \, \text{kg/m}^3 \). Therefore, the mass \( m \) of 1 m³ of water is given by: \[ m = \rho_{water} \times V_{water} \] ...
