What happens to the volume of a bicycle tire or a basketball when you use an air pump to add air?

Short Answer

Expert verified

The volume of a bicycle tire or a basketball when adding the air by a pump then volume is increases.

Step by step solution

01

Given Information

We need to explain what happens to the volume of a bicycle tire or a basketball when you use an air pump to add air.

02

Simplify

Here, apply the principle of Avogadro's law.

A direct relationship between the volume Vof the gas and the amount of the gas n. Increasing the amount of the gas it will be followed by an increase in the volume of the gas.

Avogadro's law's formula as:

V1n1=V2n2

V1is initial volume,

n1is the amount of the gas,

V2 is final volume and

n2is the amount of the gas.

Now,

When using an air pump to add air to a bicycle tire or basketball, we will increase the amount of air inside the bicycle tire or the basketball, according to Avogadro's law, an increase in the volume of the bicycle tire or the basketball.

b. The balloon floats to a higher altitude where the pressure is less (nandTdo not change).

c. All of the neon gas is removed (TandPdo not change).

d. The Kelvin temperature doubles and half of the gas atoms leak out (Pdoes not change).

e.2.0molesofO2gas is added (TandPdo not change).
