Answer:
234.4 K
Explanation:
Using the combined gas law equation as follows;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the provided information,
P1 = 1.00atm
P2 = 2.00 atm
V1 = 5.00L
V2 = 2.00L
T1 = 20°C = 20 + 273 = 293K
T2 = ?
Using P1V1/T1 = P2V2/T2
1 × 5/293 = 2 × 2/T2
5/293 = 4/T2
Cross multiply
293 × 4 = 5 × T2
1172 = 5 T2
T2 = 1172 ÷ 5
T2 = 234.4 K
