Question

2. The volume of a certain gas was found 561 cm', when pressure was 600 mm. If the pressure
decreases by 25% find new volume of gas​

Answer 1

Explanation:

$pressure \: \times volume \: = \: constant$

so 561 × 600 = ( 600 - 25% ) × new voume

that gives new volume = 561 × 600 / 450 = 748 cm'
