# If you are asked to make a very sensitive glass thermometer, which of the following working fluids would you choose? (a) mercury (b) alcohol (c) gasoline (d) glycerin

To determine
The fluid for a sensitive glass thermometer.

Explanation

Co-efficient of expansion ( Î± ) is defined as the change in volume of the body per degree rise in the temperature. The material with highest value of Î± is the one which can be used inside the glass thermometer.

Conclusion:

Co-efficient of expansion for gasoline is 0.00095â€‰Kâˆ’1 . This is the largest value of Î± among the given materials. Thus, option (b) is correct.

Co-efficient of expansion for mercury is 0.00018â€‰Kâˆ’1
