Question

you can convert a barometer into a manometer by connecting a closed tube with hg to a gas sample

Explanation:

A barometer measures atmospheric pressure with a closed - tube (usually containing Hg). A manometer measures the pressure of a gas sample. To convert a barometer to a manometer, you need to connect an open - ended tube (not a closed - tube) to the gas sample. The closed - tube in a barometer is already isolated from the gas sample (it measures atmospheric pressure). So the statement is incorrect.

Answer:

False
