Chapters 16-18 Flashcards
Describe Robert Boyle’s experiment that proved what Galileo believed, that “all bodies fall at the same speed in a vacuum.”
Boyle placed a feather and a lump of lead in a glass cylinder and pumped all the air out. When he turned the glass cylinder upside down, bot the feather and lead fell side by side.

How did Torricelli make (invent) the first barometer?
He filled a long glass tube closed at one end and open at the other end, and up-ended the tube in a dish of mercury. When he removed his finger, the mercury partially drained to a height of approximately 30 inches - the first barometer.

If a barometer at sea level measures 30 inches of mercury, and is take to a height of 18,500 ft. (3.5 miles) above sea level, the same barometer measures 15 inches of mercury. What does this mean?
Half of the atmosphere is below 18,500 feet.
