Pressure Gauge

Q. A trekker climbs up a mountain carrying a mercury barometer setup. As he goes up the mountain, the mercury column level__________.

1. goes up
2. goes down
3. remains as it is
4. goes down to zero

Q. The diagram below shows a simple mercury barometer. The mercury level is at a height $h$ when the atmospheric pressure is ${10}^5$ Pa.

What is the pressure at P?

1. 60, 000 Pa
2. 1, 00, 000 Pa
3. 14, 00, 000 Pa
4. 40, 000 Pa

Q. If we drill a hole at the top of the glass tube containing a mercury column in a barometer, the mercury level will:

1. Remain unaltered
2. Rise to the top but will not flow
3. Rise and start flowing from the hole
4. Fall down

Q.

Name the substance whose weight produces atmospheric pressure.

Q. Match the following pictures of devices to their names.

1. 
2. Siphon
3. 
4. Pressure Guage
5. 
6. Barometer

Q. Choose the correct pairs for measuring devices to their physical quantites.

1. Barometer
2. Atmospheric pressure
3. Pressure gauge
4. Liquid pressure
5. Thermometer
6. Temperature
