20 g of a substance is melted when 500 J of heat is added. What is the specific latent heat of fusion of the substance?

Explanation

To find the specific latent heat of fusion of the substance, we can follow these steps:

### Step 1: Identify the given values
- Mass of the substance (m) = 20 g
- Heat added (Q) = 500 J

### Step 2: Convert mass from grams to kilograms
Since the standard unit of mass in physics is kilograms, we need to convert grams to kilograms:
