All changes saved A gas is at 275 K, and its temperature is raised to 400 K. The volume is measured at 5.82 L after the gas is heated. What is
the volume of the gas before it is heated?
8.25 L
12.0L
2.00 L
4.00 L

4.00L

Explanation:

Using Charle's law, which have the following equation:

V1/T1 = V2/T2

Where;

V1 = initial volume (litres)

T1 = initial temperature (Kelvin)

V2 = final volume (litres)

T2 = final temperature (Kelvin)

According to the information provided, T1 = 275K, T2 = 400K, V1 = ?, V2 = 5.82L

Hence, using the formula;

V1/275 = 5.82/400

400 × V1 = 275 × 5.82

400V1 = 1600.5

V1 = 1600.5 ÷ 400

V1 = 4.001

Therefore, volume of the gas before it is heated is 4.00L

the answer is   c.) 1575 j.
