1. a) Write the advantage of using mercury as a thermomertic fluid.
b) Difference between Beam balance and electronic balance.
c) Define Parallax error. ​

Answer 1

Answer:

The uses of Mercury as thermomertic fluid is that the Mercury has high melting and boiling point so

It can easily measure the temperature

• Beam balance is a old tool with simple work while electronic balance is a modern device
• Beam balance does not give accurate measurements while electronic balance give accurate measurements

Parallax error is a displacement or difference in the apparent position of an object viewed along with two different lines of sight
