What temperature corresponds to standard conditions for a gas?

Standard conditions for a gas are defined as a temperature of 0°C, which is equivalent to 273.15 K, and a pressure of 1 atm. This standardization is crucial in chemistry, particularly in relation to the Ideal Gas Law and any calculations involving the behavior of gases. At this temperature, the properties and behavior of gases are predictable and can be compared effectively in scientific studies.

The other temperatures provided do not align with this definition of standard conditions. For example, while 25°C is often used in many laboratory conditions and for standard state calculations, it is not the official standard temperature for gases. Thus, recognizing that 0°C is the accepted temperature for standard gas conditions allows for consistency in experiments and discussions regarding gas behaviors.
