Here is a two part problem I'm having trouble with:(adsbygoogle = window.adsbygoogle || []).push({});

The length of the column of mercury in a thermometer is 4cm when the thermometer is immersed in ice water and 23.5cm when the thermometer is immersed in boiled water.

a) What should be the length at room temperature 22degreesCelcius?

I did ratio calculation to find this and got 8.23cm and it was correct

Here is where I'm stuck:

b) if the mercury column is 25.2cm long when the thermometer is immersed in a chemical solution, what is the temperature of the solution (answer in deg.Celsius)

Again i tried doing a ratio: 100degC = 23.5cm

xdegC = 25.2cm

my answer was 107.23degC and I is incorrect...though it makes sense and seems correct to me logically...I'm not really sure where to go from here any advice????
