Question

Complete the second row of the table.Express the volume in liters to three significant figures.

Answer 1

In this case you need to use the volume and temperature equation from Charles law.

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

We are given T1 = 139 k

T2= 317 k

V2= 176 L

We want to find V1. Now lets re-arrange the equation.

`V_1=(V_2)/(T_2)xT_1`

V1 = (176 x 139)/317

V1= 77.2 L
