In a flexible container , 15.9 L of gas is under 589 kPa of pressure at a temperature of 56.5 degrees * C . If the pressure and temperature change to STP , what is the new volume ? A 10.2 B 92.4L 112 D 76.6 L

76.6 litres is the volume of the gas if pressure and temperature changes to STP.

Explanation:

Data given:

Volume of the gas V1 = 15.9 litres

pressure of the gas P1 = 589 kPa or 5.81 atm.

temperature T1 = 56.5 degrees or 329.3 K

Final pressure P2 = 101.3 kPa

Final temperature T2 = 273 K

At STP the pressure is 1 atm or 101.3 kPa and the temperature is 273 K. So from the question the final temperature and pressure is at STP.

from Gas Law:

 =  

V2 =

Putting the values in  the above rearranged equation of Gas Law:

V2 =

    = 76.6 Litres

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
