**How do you calculate Q value?** To calculate the heat transfer **Q**, use the appropriate formula based on the situation. For temperature changes, use **Q = mC∆T**; for phase changes, use **Q = mL**.

**Is enthalpy the same as Q?** Enthalpy (**H**) is related to heat transfer **Q**, but they are not exactly the same. Enthalpy includes internal energy and pressure-volume work, whereas **Q** specifically refers to heat transfer.

**What is Q in specific heat capacity?** In the context of specific heat capacity, **Q** represents the heat transferred to or from an object due to a temperature change. It can be calculated using **Q = mC∆T**.

**What are the two methods of vaporization?** The two methods of vaporization are:

**Boiling**: Vaporization that occurs throughout the liquid, leading to the formation of bubbles and conversion to vapor.**Evaporation**: Vaporization that occurs only at the liquid’s surface, where high-energy molecules escape into the vapor phase.
