Steam at `100^(@)C` is passed in 500 g of water at `15^(@)C` till it starts boiling. What is the final amount of boiling water?

Explanation

To solve the problem of finding the final amount of boiling water when steam at 100°C is passed into 500 g of water at 15°C until it starts boiling, we can follow these steps:

### Step 1: Identify the heat given by the steam
When steam condenses, it releases heat. The heat given out by the steam can be calculated using the formula:
\[ Q_{\text{steam}} = m \times L \]
where:
- \( m \) = mass of steam (in grams)
- \( L \) = latent heat of vaporization of steam (approximately 540 cal/g)
