Understand that STP (Standard Temperature and Pressure) is a set of conditions commonly used in chemistry to allow comparison of experimental data.
Recall that the standard temperature is defined as 0°C, which is equivalent to 273.15 K.
Recognize that the standard pressure at STP is 1 atm, which is also equal to 760 mmHg or 101.325 kPa.
Note that 100°C and 1 atm is not STP but rather the boiling point of water at 1 atm pressure.
Conclude that the correct description of STP is 0°C and 1 atm (or equivalently 0°C and 760 mmHg).
