Explanation:

For the first question, we can see that the pressure is constant so we apply Charles law;

V1/T1 =V2/T2

V1T2 = V2T1

V1= 4.5 L

T1= 27 + 273 = 300 K

V2= ?

T2= 127 + 273 = 400 K

V2= V1T2/T1

V2= 4.5 × 400/300

V2= 6L

For question 2, Charles law is also used;

V1/T1 =V2/T2

V1T2 = V2T1

T1= 338 K

V1= 0.480 L

T2= ?

V2= 9.2 L

T2= V2T1/V1

T2= 9.2 × 338/0.480

T2= 6478.3 K
