Answer 2

Calculation of Heat Released during Condensation of Water Vapor

To calculate the amount of heat released during the condensation of water vapor, we can use the formula:

Q = m * L

Where: - Q is the heat released (in joules) - m is the mass of the water vapor (in kilograms) - L is the latent heat of vaporization of water (in joules per kilogram)

Given that the mass of the water vapor is 2.5 kg, we need to find the latent heat of vaporization of water at 100°C.

According to the search results, the latent heat of vaporization of water at 100°C is approximately 2.3 * 10^6 J/kg.

Using the formula, we can calculate the heat released during the condensation:

Q = 2.5 kg * 2.3 * 10^6 J/kg

Calculating this, we find:

Q ≈ 5.75 * 10^6 J

Therefore, approximately 5.75 * 10^6 joules of heat will be released during the condensation of 2.5 kg of water vapor taken at 100°C.

Please note that the values used in this calculation are approximate and may vary slightly depending on the specific conditions and properties of water vapor.
