Question

Given 300mL of a gas at 17.0 degrees Celsius, what is the volume at 10 degrees Celsius if the pressure remains constant?

Answer 1

292.75mL

Explanation:

From the ideal gas equation

PV= nRT

With each symbols having standard meaning

For pressure remaining constant the equation for two states can be written as

`(V_1)/(T_1)=(V_2)/(T_2)`

Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K

Now plugging values in above equation to find V_2

`(300)/(290) =(V_2)/(283)\\V_2 =(300)/(290)*283 = 292.75mL`

Therefore, the volume at 10 degrees Celsius = 292.75mL
