The length of the mercury thread is found to be 4cm and 24cm at ice point and steam point respectively on an ungraduated thermom eter.What is the temperature corresponding to a length of 8cm?
1 answer:
Answer:
The difference between ice and steam in Celsius (Centigrade) is 100 deg.
So the difference between and 4 cm and 24 cm of the thread corresponds to 100 deg C.
So 8 cm is 4 cm greater than the ice point
4 cm / 20 cm = 1/5 since the steam point and the ice point are 20 cm apart
Then 1/5 * 100 deg C = 20 deg C the requested temperature
