The temperature of water at the bottom of a lake whose upper surface has frozen to ice would be around

What is the temperature at the bottom of a lake when water gets frozen with -ve temperature in the- atmosphere?

Consider the situation of the previous problem. Assume that the temperature of the water at the botton of the lake remains contant at 4^(@)C as the ice forms on the surface (the heat required to maintain the temperature of the bottom layer may come from the bed of the lake). The depth of the lake is 1.0m. Show that the thickness of the ice formed attains a steady state mamimum value. Find this value. The thermal conductivity of water =0.50Wm ^(-1) ^(@)C^(-1) . Take other relevent data form the previous problelm.

The temperature of water at the surface of a deep lake is 2^C . The temperature expected at the botton is

The temperature of water at the surface of a deep lake is 2^@C . The temperature expected at the bottom is

The temperature of water at the surface of deep lake is 2 °C. The temperature expected at the bottom is

The temperature of water at the surface of a deep lake is 2^@C . The temperature expected at the bottom is

Temperature of water at the surface of lake is – 20°C. Then temperature of water just below the lower surface of ice layer is
