Boyle's Law states that the volume of a given mass of gas at constant temperature is inversely proportional to the pressure applied to the gas. Mathematically, it can be expressed as (PV = k), where (P) is pressure, (V) is volume, and (k) is a constant. This law demonstrates the relationship between pressure and volume of a gas when temperature and quantity of gas are held constant.
What is Boyle's Law all about?
Boyle's Law states that the volume of a given mass of gas at constant temperature is inversely proportional to the pressure applied to the gas. In simpler terms, as the pressure on a gas increases, its volume decreases, and vice versa.
How can Boyle's Law be mathematically represented?
Boyle's Law can be mathematically represented as P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume, respectively.
What is the significance of the constant 'k' in Boyle's Law?
The constant 'k' in Boyle's Law represents the proportionality constant and varies for different amounts of the same gas. It helps maintain the relationship between pressure and volume for a fixed amount of gas at a constant temperature.
How is Boyle's Law experimentally verified?
Boyle's Law is experimentally verified by observing that at a constant temperature, the volume of a given quantity of gas decreases proportionally with an increase in pressure, as demonstrated in Fig (3.1) of the document.
What happens to the volume of a gas according to Boyle's Law when the pressure is doubled?
When the pressure on a gas is doubled, according to Boyle's Law, the volume of the gas is halved. This inverse relationship between pressure and volume is a fundamental principle in understanding gas behavior.
