The length of the column of mercury of in a thermometer is 2cm when the thermometer is immersed in ice water and 24cm when the thermometer is immersed in boiled water. What should be the length at room temperature, 22 deg C? Answer in units of cm.

If the mercury column is 261 cm long when the thermometer is immersed in a chemical solution, what is the temperature of the solution? Answer in units of deg C.

Thanks in advance :)

I'm doing these UT assignment questions, and your answers seem to be incorrect. I appreciate your help, although I do understand your methods.

Well if we are assuming that the ice water is 0 degrees and the boiling water is 100 degrees, we can say that the difference between 100 degrees is 22 cm, so that makes .22cm a degree, so .22*22=4.84 cm.

If the column is 261 cm then we just divide by the .22
so: 261/.22=1186.3636 ("36" recurring) Degrees

I hope that answered your question
