A gas occupies 200 mL at -73.0°C. To have the same gas occupy 300 mL, should the temperature be increased or decreased? What is the new temperature in Kelvins? K

Given:
Volume 1 = 200mL
Temperature 1 = -73.0°C or 200.15 K
Volume 2 = 300 mL
Determine the new temperature.
Charles's Law Formula:
V1/T1 = V2/T2
T2 = V2 T1 / V1
Since we are given the temperature and the volume, it means that we will be using Charles's Law which states that the volume of gas expand as the temperature increases. Hence temperature is directly proportional to volume.
Solution:
Substitute the given values of v1, v2 , and t1 to the formula for t2.
T2 = ((300 mL)(200.15 K))/200 mL
T2 = 60,045 mL.K/200mL
T2 = 300.225 K
Final answer:
T2 = 300.225 K
