Define and compare boiling point, melting point, and freezing point.
Answer (3)
Boiling point of a substance is the temperature at which it converts from liquid to gas. Melting point is the temperature at which a substance converts from solid to liquid. Freezing point is just the opposite of melting point, it is the temperature at which a substance converts from liquid to solid. Hope I could help!
Boiling point is the temperature at which a liquid turns into gas, while melting point is when a solid turns into a liquid. The freezing point is essentially the same as the melting point but in reverse, turning a liquid to a solid.
Boiling point, melting point, and freezing point are important physical properties of substances.
Boiling Point
The boiling point is the temperature at which a liquid changes phase to become a gas.
At this temperature, the liquid and gas phases of the substance are in equilibrium.
The stronger the chemical bonds and intermolecular forces in a substance, the higher its boiling point will be.
Melting Point
The melting point is the temperature at which a solid changes its phase to become a liquid.
Conversely, the freezing point is the temperature at which a liquid changes to a solid. In both cases, the solid and liquid phases are in equilibrium.
Stronger chemical bonds and intermolecular forces in the substance result in a higher melting point.
Freezing Point
The freezing point is essentially the melting point but considered in the reverse direction, where a liquid becomes a solid.
At this temperature, equilibrium exists between the liquid and solid phases.
Usually, for a pure substance, the melting point and freezing point are the same.
Understanding these points helps in determining the state (solid, liquid, or gas) of a substance at a given temperature and provides insights into the strength of intermolecular forces within the substance.
The boiling point, melting point, and freezing point are critical temperatures at which substances change states. The boiling point occurs when a liquid transitions to gas, the melting point is when a solid becomes a liquid, and the freezing point is when a liquid turns into a solid. For example, water boils at 100°C and freezes/melts at 0°C under normal pressure conditions.
