Question

A 3.0 L container holds a sample of hydrogen gas at 300 K. If the temperature decreases to 100 K and the pressure remains constant, what will the volume be? (Points : 3) 0.1 L 0.3 L<-- I thinks its this 1.0 L 9.0 L

Answer 1

At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

 

T1 / V1 = T2 / V2

 

V2 = T2 x V1 / T1

 

V2 = 100 x 3.0 / 300

 

V2 = 1.0 L

Hope this answers the question. Have a nice day.
