<u>The pressure increased to 450 Kilo pascals.</u>
<h3>Explanation:</h3>
This the condition of Boyle's law:
P1V1 = P2V2
By putting values in above formula:
= 300 * 75 = P2 * 50
= P = 300 * 75/50
= p = 450 Kilo pascals
In this question description, two variables volume and pressure are involved while the temperature remains constant. So it is the condition of <em><u>Boyle's law which states that the Pressure and volume of a gas are inversely proportional if the temperature of the gas remains constant.</u></em>
