Question

Bottom of a lake is at 0°C and atmospheric temperature is -20°C. If 1 cm ice is formed on the surface in 24 h, then time taken to form next 1 cm of ice is (1) 24 h (2) 72 h (3) 48 h (4) 96 h

Answer 1

Answer:

48 h mate I will be there at a point where I can get a point to be there at a point where I

Answer 2

Time taken to form next 1 cm of ice = 24h

Given:

Bottom of a lake is at 0°C and atmospheric temperature is -20°C.

If 1 cm ice is formed on the surface in 24 h.

To find:

Time taken to form next 1 cm of ice.

Explanation:

Latent heat:

Form of internal energy stored by evaporated or melted water.

A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of ice.

So for first layer 1cm volume is same that of second layer of 1cm

So it also required 24h to form 1cm height ice

Time taken to form next 1 cm of ice = 24h
