1. What is Condensation Heat?

Condensation heat is the energy released when a substance changes from its gaseous phase to its liquid phase. This energy is equal to the latent heat of vaporization for the substance.

2. How Does the Calculator Work?

The calculator uses the condensation heat equation:

Where:

• \( Mass \) — Mass of the substance (grams)
• \( Latent Heat \) — Latent heat of vaporization (Joules per gram)

Explanation: The equation calculates the total energy released during condensation by multiplying the mass of the substance by its specific latent heat of vaporization.

3. Importance of Condensation Heat Calculation

Details: Calculating condensation heat is important in thermodynamics, HVAC systems, power plant design, and various industrial processes where phase changes occur.

4. Using the Calculator

Tips: Enter mass in grams and latent heat in Joules per gram. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is latent heat of vaporization?
A: It's the amount of energy required to convert 1 gram of a liquid into vapor without temperature change.

Q2: How does condensation heat relate to evaporation?
A: The heat released during condensation is exactly equal to the heat absorbed during evaporation for the same amount of substance.

Q3: What are typical latent heat values for common substances?
A: Water: 2260 J/g, Ethanol: 841 J/g, Ammonia: 1371 J/g at their boiling points at 1 atm.

Q4: Why is condensation heat important in meteorology?
A: It's a major source of energy in atmospheric processes, powering weather systems and storms.

Q5: Does pressure affect latent heat values?
A: Yes, latent heat values vary with pressure, though for many applications at constant pressure we use standard values.
