Because copper is good conductor of heat and it has low specific heat capacity

copper is a good conductor of heat so the vessel soon acquires the temperature of its contents.Copper also has low specific heat capacity so the heat capacity of calorimeter is low and the amount of heat energy taken by the calorimeter from its contents to acquire the temperature of its contents is negligible.

firstly copper is a good conductor of electricity so the vessel of the calorimeter soon acquires the temp of its contents and secondly it has a low specific heat capacity so that the heat capacity of the calorimeter is low and the amount of heat energy taken by the calorimeter by its contents to acquire the temp of its contents is negligible.

Copper has a negligible specific heat capacity. Hence, it takes negligible heat from it’s surroundings to reach the same temperature as the contents of the calorimeter.
Therefore, almost no heat is lost to the surroundings and hence,
Heat lost by the body = Heat gained by the calorimeter; and vice versa. 🙂

It take a negligible amount of heat from its contents to acquire the temperature of its contents

There are two reasons :
1) copper is a gud conductor of heat
2) it has low specific heat capacity , therefore does no absorb heat from the substance .

dry seed swells up when soaked in water . why ? what’s the answer – imbibtion or endosmosis or both .

Ujjwala,
I would say that the answer is merely imbibation. Endosmosis means osmosis, which only takes place through a semi-permeable membrane. However, not all seed coats are permeable to water or are semi-permeable. Hence, according to me, the answer is imbibation.
Hope this helped! Thank you and keep visiting! 🙂
