Question

The air pressure inside a balloon is 0.78 atm. What is this

Answer 1

Answer:

The pressure in mmHg is 59.

Explanation:

Given data:

Pressure of air inside balloon = 0.78 atm

Pressure in mmHg = ?

Solution:

mmHg:

mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.

Symbol:

"mmHg"

Atmosphere (atm)

atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.

1 atm = 760 mmHg

Inorder to convert the atm into mmHg we will multiply the given atm value with 760.

0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg

59 mmHg or 59
