Answer:
a. The temperature should be increased.
b. 342.86K
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question, the following information were given:
V1 = 210mL
V2 = 360mL
T1 = -73°C (-73 + 273 = 200K)
T2 = ?
Using V1/T1 = V2/T2
210/200 = 360/T2
Cross multiply
200 × 360 = 210 × T2
72000 = 210T2
T2 = 72000/210
T2 (new temperature) = 342.86K
