What is the same as the freezing point of water?

The melting point of a substance is the temperature at which it transitions from a solid to a liquid. For water, this point is the same as its freezing point, where it transitions from a liquid to a solid. Both occur at 0 degrees Celsius (32 degrees Fahrenheit) under standard atmospheric conditions; thus, they represent the same physical property of water.

When discussing the other options, the boiling point refers to the temperature at which water turns from a liquid to a gas (100 degrees Celsius or 212 degrees Fahrenheit at sea level), while the condensation point is where a gas converts back into a liquid. The evaporation point is not defined as a specific temperature but rather describes the process when molecules at the surface of a liquid gain enough energy to enter the gas phase at any temperature, which also does not equate to a fixed temperature like the freezing point does.
