Answer 1

Answer:

(a)This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.

(b)For a gas, the relationship between volume and pressure (at constant mass and temperature) can be expressed mathematically as follows.

P ∝ (1/V)

Where P is the pressure exerted by the gas and V is the volume occupied by it. This proportionality can be converted into an equation by adding a constant, k.

P = k*(1/V) ⇒ PV = k

The pressure v/s volume curve for a fixed amount of gas kept at constant temperature

(c) give in picture

(d)Boyle's Law states that when the temperature is kept constant, the relationship between volume and pressure is inversely proportional. As the volume decreases, the pressure increases, meaning as the one doubles, the other halves. This law aided in the invention of syringes and explains the science behind balloons, plane travel and bubbles.
