Question

4. A bicycle pump contains 200 cm of air and is
connected to a bicycle tyre.
The volume of the tyre is 800 cm3.
The pressure of the air in the tyre (it is 'flat') is
1.0 atmosphere, the same as the air in the pump.

a) What is the total volume of the air initially?
b) What is the volume of air after the pump is

(= volume,)

pushed in? (= volume2)

Answer 1

Answer:

The total volume of the air is 1000 cubic centimeters.

Explanation:

Since the bicycle pump and the bicycle tyre have the same pressure, then the total volume of the air is the sum of the volume of each element, then we translate this into the following artihmetical expression:

V = 200\,cm^{3}+800\,cm^{3}

V = 1000\,cm^{3}

The total volume of the air is 1000 cubic centimeters.
