Answer:
1.04 L
Explanation:
Charles law states that for a fixed mass of gas, volume of gas is directly proportional to the absolute temperature at constant pressure.
[tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex]
where V1 is the volume and T1 is absolute temperature at first instance
and V2 is volume and T2 is absolute temperature at the second instance
Absolute temperature is temperature in the kelvin scale
T1 - 25 °C + 273 = 298 K
T2 - -15 °C + 273 = 258 K
substituting the values in the equation
[tex]\frac{1.2 L}{298K} = \frac{V2}{258K}[/tex]
V2 = 1.04 L
when the temperature is -15 °C the volume is 1.04 L
