3.50 liters of a gas at 727.0 K will occupy how many liters at 153.0 K?
miv72 [106K]

Answer:

0.737 L

Explanation:

Charles law states for a fixed amount of gas, volume of the gas is directly proportional to the absolute temperature of the gas at constant pressure

we can use the following equation

V1/T1 = V2/T2

where V1 is volume and T1 is temperature at first instance

V2 is volume and T2 is temperature at the second instance

substituting the values

3.50 L / 727.0 K = V2 / 153.0 K

V2 = 0.737 L

new volume at 153.0 K is 0.737 L
