Aballoon has a volume of 1.2 liters inside a room where the temperature is 25°c. what is the volume of this balloon when it is taken outdoors on a very cold day where the temperature is -15°c?

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.

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

V2 = 1.04 L

when the temperature is -15 °C the volume is 1.04 L

the correct answer would be d. hope this !
