If a tire pump whose cylinder has a volume of 2.0 liters at 1 atmosphere of pressure

compresses the air to a volume of 0.50 liters without releasing any of the air, what is

the resulting pressure of the air in the cylinder?

The resulting pressure of the air in the cylinder is 4 atmosphere.

Step-by-step explanation:

Given : If a tire pump whose cylinder has a volume of 2.0 liters at 1 atmosphere of pressure  compresses the air to a volume of 0.50 liters without releasing any of the air.

To find : What is  the resulting pressure of the air in the cylinder?

Solution :

Let and represent the pressure and volume of the gas at an initial state .

and represent the pressure and volume of the gas at an final state .

According to Boyle's Law,

Substitute,

Therefore, the resulting pressure of the air in the cylinder is 4 atmosphere.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

probably .5

i can on others if necessary.
