The reaction of methltrichloroacetate with sodium methoxide (NaOMe) generates

A cylinder of height h is filled with water and is kept on a block of eight h/2. The level of water in the cylinder is kept constant. Four holes numbered 1, 2, 3 and 4 are at the side of cylinder and at height 0, h/4, h/2 and 3h/4 respectively. When all four holes are opened together, the home from which water will reach farthest distance on the plane PQ is the hole no.

The pressure p, volume V and temperature T for a certain gas are related by p = , where A and B are constants. The work done by the gas when the temperature changes from T₁ to T₂ while the pressure remains constant, is given by
