We apply Boyle Mariotte's law, where for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2 P2=( P1 x V1)/V2 1 L-----1000L--->( 140ml/1000ml)x1L=0,140 L
Potential energy<span> is the </span>energy<span> that is stored in an object due to its position relative to some zero position. It is calculated by the expression as follows:
PE = mgh PE = 25 (9.8) (3) PE = 735 J
Hope this answers the question. Have a nice day.</span>
