Question

A gas is sealed in a bottle at 25°C and 1.50 atm pressure. How must the storage conditions be changed to bring the gas to Standard Temperature and Pressure (STP)?

A. Increase the temperature by 25°C and decrease the pressure by 0.514 atm.
B. Keep the temperature the same and increase the pressure by 98.5 atm.
C. Decrease the temperature by 25°C and decrease the pressure by 0.500 atm.

Answer 1

The answer is C.

Step-by-step explanation:

Answer 2

Answer: The correct option is (C).

Step-by-step explanation:

At STP, condition the the value of pressure is taken to be 1 atm.

At STP, condition the the value of Temperature is taken to be 0° C that is 273 K.

So, in order to keep the gas sealed under the bottle at STP, Temperature should decreases by the 25°C and pressure should decreased by 0.500 atm.

Temperature to be kept at= 25°C - 25°C = 0°C

Pressure to be kept at =1.50 atm - 0.500 atm =1.000 atm

Hence, the correct option is (C).
