Hint: First, use the ideal gas equation. Try to find the relation between variables. Do understand the meaning of Boyle’s law in it. You can relate this law to our daily life examples. Basically, Boyle’s law states that when pressure increases, volume decreases.
Complete step by step solution:
According to ideal gas equation,
The relationship between pressure, volume and temperature is called as ideal gas equation.
Where,
P = pressure
V = volume
R = universal gas constant
n = number of moles
T = temperature
Boyles’s state that at constant temperature, the volume of a given mass of a gas is inversely proportional to its pressure.
Mathematically.
It means that when we increase pressure then the volume will decrease and vice versa.
There are many daily life examples of Boyle’s law few of them are listed below
1. Drawing fluid into the syringe. When a doctor gives an injection, he presses the plunger outward so that air pressure inside the syringe decreases and the volume of air increases. Thus the fluid outside of the syringe is sucked into the barrel until the interior and exterior pressure are balanced. Now by pressing the plunger, the inside air pressure increases, which will result in a decrease in its volume, and it pushes the liquid out.
2. Another real-life application of Boyle’s law is observed when we fill the air in the tires of a bike. When we pump air, the pressure inside the tire increases and air molecules get compressed.
Note: According to the ideal gas equation. Volume is inversely proportional to pressure and directly proportional to temperature. R is the universal gas constant and its value does not change with gases.
