A solid metal weighing 150 g melts at its melting point of `800^(@)C` by providing heat at the rate of 100 W. The time taken for it to completely melt at the same temperature is 4 min. What is the specific latent heat of fusion of the metal ?

Explanation

To find the specific latent heat of fusion of the metal, we will follow these steps:

### Step 1: Identify the given values
- Mass of the metal (m) = 150 g
- Power (P) = 100 W
- Time (t) = 4 minutes = 4 × 60 seconds = 240 seconds

### Step 2: Calculate the total heat energy supplied
