Question

Complete the fourth row of the table.Express the temperature in degrees Celsius to three significant figures.

Answer 1

For this question we are given:

T2 = 11.4 degrees celsius

V1 = 14.8 cm3

V2=19.9 cm3

We want to know T1. So we need to use Charles Law:

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

Now if we re-arrange:

`T_1=(T_2V_1)/(V_2)`

So T1 = (11.4 x14.8)/19.9

T1 = 8.48 degrees celsius
