Ice melts at the rate of 5 kg per hour in a cold storage when the temperature outside is 300 K. Calculate the minimum power of the motor is to be used to drive a refrigerator to just prevent the melting of ice. Specific latent heat of usion of ice `=3.3 xx 10 ^(5) J kg ^(-1) .[E.Q]`

Explanation

To solve the problem of calculating the minimum power of the motor required to drive a refrigerator to prevent the melting of ice, we can follow these steps:

### Step 1: Understand the Problem
We need to prevent the melting of ice that melts at a rate of 5 kg per hour. The specific latent heat of fusion of ice is given as \( L = 3.3 \times 10^5 \, \text{J/kg} \).

### Step 2: Calculate the Heat Required to Melt Ice
The heat \( Q \) required to melt the ice can be calculated using the formula:
\[
