The main reason is the high level of CO₂ that is contained in the breath as well as the effect of the blowing of taking away the air around the candle that is higher in O₂ than the air coming out with the breath

According to Boyle's law, for a fixed quantity of gas at a given temperature, what quantity relating pressure P and volume V is
yan [13]

<u>Answer:</u> The quantity relating pressure and volume is PV=k and the size of the tank must be 1.92\times 10^3L

<u>Explanation:</u>

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

P\propto \frac{1}{V}

Or,

PV=k

The equation given by this law is:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume.

P_2\text{ and }V_2 are final pressure and volume.

We are given:

P_1=160atm\\V_1=12L\\P_2=1atm\\V_2=?L

Putting values in above equation, we get:

160atm\times 12L=1atm\times V_2\\\\V_2=\frac{160\times 12}{1}=1920L=1.92\times 10^3L

Hence, the size of the tank must be 1.92\times 10^3L
