The amount of heat required to convert 1 g of any substance from the liquid to the gaseous state is defined as __________.
A
the specific heat of that substance
B
1 calorie
C
surface tension
D
the heat of vaporization of that substance
Verified step by step guidance1
Understand the concept of heat of vaporization: It is the amount of energy required to convert a substance from its liquid phase to its gaseous phase without changing its temperature.
Recognize that the heat of vaporization is specific to each substance and is usually expressed in units such as calories per gram or joules per gram.
Differentiate between related terms: Specific heat refers to the amount of heat required to change the temperature of a substance, while surface tension is a measure of the cohesive forces at the surface of a liquid.
Identify that 1 calorie is a unit of energy, but it is not specifically related to the phase change from liquid to gas unless specified as the heat of vaporization.
Conclude that the correct term for the energy required to convert 1 g of a substance from liquid to gas is the heat of vaporization.
