# The volume of a gas is 605 liters at 27.0C. The new temperature is -3.0C. What is the new volume?

-67.2 L, -545 L, -672 L, -5450 L

**Solution:**

As per Charles' law of gases, we know that the volume of a gas is directly proportional to the temperature when pressure and amount of substance are constant.

The formula which can be used here is

V_{1}/T_{1} = V_{2}/T_{2}

V_{1} = 605 L

T_{1} = 27.0C

T2 = -3.0C

Converting the temperature from Celcius to Kelvin

T_{1} = 27.0C = 300 K

T2 = -3.0C = 270 K

By substituting the values

605/300 = V2/270

By cross multiplication

V2 = (605 × 270)/ 300

So we get

V2 = 544.5 ≈ 545 L

Therefore, the new volume is 545 L.

## The volume of a gas is 605 liters at 27.0C. The new temperature is -3.0C. What is the new volume?

-67.2 L, -545 L, -672 L, ;-5450 L

**Summary:**

The volume of a gas is 605 liters at 27.0C. The new temperature is -3.0C. The new volume is 545 L.
