Calculate Latent Heat (Q)



Formula

The formula to calculate Latent Heat (Q) is:

\[ Q = m \times L \]

What is Latent Heat?

Latent heat refers to the amount of heat absorbed or released by a substance during a phase change, such as from a solid to a liquid or a liquid to a gas, without a change in temperature. This energy is used to break or form the intermolecular bonds in the substance, allowing it to transition between phases. Unlike specific heat, which causes a temperature change, latent heat is solely associated with phase transitions.

Example Calculation

Let's consider an example:

Using the formula to calculate Latent Heat:

\[ Q = 2 \times 2260 = 4520 \, \text{Joules} \]

This means that 4,520 Joules of energy is required for 2 kg of water to turn into steam.
