Answer to Question 1

TRUE

Answer to Question 2

A public of Galileo's, Torricelli noted that pumps in mines were able to pull water upward to a height of about 10 m. However, the level fluctuated day to day. Torricelli hypothesized that the weight of the air varied with weather conditions and that the weight determined the height in the pipe. To simulate, he used mercury and a 1 m glass tube. He sealed the tub at one end, filled it with mercury, inverted it into a dish containing mercury forming a vacuum. He found the average height of mercury in the tube was 760 mm depending on the weather. Thus was born the first mercury barometer. An aneroid barometer doesn't use liquid, instead by a chamber, attached to a gauge, containing a small amount of air. As air pressure increase, it presses inward on the chamber and when it decreases, it relieves pressure on the chamber. These changes cause the needle on the gauge to move.
