Agas 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.

The correct option is (C).

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).

The answer is C.
