Question

If the temperature is held constant the relationship between pressure and volume is

Answer 1

Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant. If volume increases, then pressure decreases and vice versa, when temperature is held constant.

Answer 2

If the temperature is held constant, the pressure and volume are inversely proportional to each other.

• It is Boyle's law that gives the relationship between pressure and volume of a fixed mass of gas when the temperature is kept constant.
• According to Boyle's law, "the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature".
• Expressed mathematically, pv = c (constant). Or, it can also be written as, $p_1v_1=p_2v_2$, where, 1 and 2 represent initial and final states of a fixed amount of gas.
• So, it can also be said that the product of pressure and volume is constant when the temperature is fixed.
