Explanation :
In thermodynamics, a system is region or part of space which is being studied and observed while the surrounding is the region or space around the system which interacts with the system.
Here in the experiment ,system which is observed is reaction or changes when citric acid and sodium bicarbonate are mixed together. And the mixing is carried out in the calorimeter which serves as a surrounding around the system.
The reason behind the using the calorimeter is measure the energy change occurring during the reaction.
It causes the water to evaporate from the earths surface so that it can cycle through again
Answer:
Due to how big the glacier is you would need more heat to melt it and since the ice cube is smaller a small amount of heat would melt it
