It is called a barometer. Inside this instrument is a small, flexible metal capsule. It is called an aneroid cell.

This is barometer. It is small and it is flexible metal capsulre. The man who invented it was Evangelista Torricelli. He found this theory when he walked by a pump on day.

The device used to measure pressure is a barometer. Evangelista Torricelli is the guy that came up with the theory. This theory came to him because he walked next to a pump that was pumping water along the road.

It is called the gas pressure sensor. Evangelista Torricelli invented it. He saw a pump one day and just thought of it. What a smart cookie!

It's called a barometer. It was made by Evangelista Torricelli. I wrote about him in my paper. He used mercury to show the difference in pressure. It proved that air weighed something.

The barometer is the instrument. That is why on the Weather Channel they talk about the barometric pressure. It was invented by Evangelista Torricelli.

We use a barometer. Evangelista Torricelli founded the baromenter. He thought of this theory because it measured the amount of pressure in an object.
