Guida verificata passo dopo passo1
Understand that the melting point of a substance is the temperature at which it changes from solid to liquid at a given pressure.
Recognize that the problem specifies standard atmospheric pressure, which is 1 atm.
Recall that for pure water (H\_2O), the melting point under 1 atm pressure is a well-known physical constant.
Note that the melting point of ice is commonly given as 0 °C, which is equivalent to 32 °F, but the problem asks for the temperature in °C.
Conclude that under standard atmospheric pressure, pure ice melts at 0 °C.
