In the above paper i dont understand Q.15 related to temperature. CAn someone plz explain.

Assuming that the expansion of the mercury is proportional to change in temperature indicated by the thermometer,
=((15/25)*120)-10
=62 degrees Celsius.

plz explain. THis answer was written in the past papers book as well but i dont understand it.

This has been already explained in another topic, I guess. :roll:

 

[SMRJ]

Use this formula,
(((Thermometric property at unknown temperature)-(Thermometric property at 0 degrees Celsius))/((Thermometric property at 100 degrees Celsius)-(Thermometric property at 0 degrees Celsius)))*100=Temperature/degrees Celsius.

This is a bit confusing, but i hope you understand, if not contact ,e with the information provided at the right hand side.
