What is the temperature of this gas if the molecules have merge kinetic energy of 631 10" 20L (vinder What is the pressure in the tank? Continue on back if necessary

Answer 1

first question of the image posted is being answered here.

From Ideal Gas equation

P * V = n * R * T

for the given states

P1 = 1.2 atm

V1 = 4.0 m³

T1 = 27 + 273 = 300 K

P2 = 0.5 1.2 = 0.6 atm

V2 = to be find out

T2 = 127 + 273 = 400 K

( P1 * V1 ) / T1 = ( P2 * V2 ) / T2

so V2 = ( P1 * V1 * T2 ) / ( T1 * P2 )

V2 = ( 1.2 * 4 * 400 ) / ( 300 * 0.5 * 1.2 )

V2 = 10.667 m³
