Final answer:
The statement is false, as the correct standard temperature and pressure (STP) are 0°C and 1 atm, not 25°C and 1 atm. STP is essential for comparing the properties of gases.
Step-by-step explanation:
The statement is false. The currently accepted standard temperature and pressure (STP) for a gas are 0°C (273.15 K) and 1 atm pressure, not 25°C. Therefore, the correct STP values are 0°C and 1 atm, which is equivalent to a temperature of 273.15 K and a pressure of 101.325 kPa or 1 bar which is close to, but not exactly, 1 atm.
It's important to note that the volume of 1.000 mole of an ideal gas at STP is approximately 22.4 L, according to the standard molar volume. However, for simplicity and historical context, 1 atm is sometimes still used as standard pressure in some contexts, despite the official change to 1 bar.
