Standard temperature for gas

Standard temperature for gas

• A. 0 degree Celsius
• B. 0 Kelvin
• C. 273 Kelvin
• D. A and C

Answer: (D)

Standard temperature for gas is the point at which the gas calculations are often set: 0°C, which is the same as 273.15 K. Because temperature can be read on either scale, 0°C and 273.15 K describe the same temperature. In many contexts, 273 K is used as a rounded value for simplicity, so both 0°C and 273 K are acceptable as standard temperatures. 0 Kelvin is absolute zero, the lowest possible temperature where molecular motion essentially stops, and it’s not used as a standard temperature for gas calculations. Hence both 0°C and 273 K represent the standard temperature.
