Answer 1
Correct Option: A) The water received more energy than the alcohol.

Reason:
In the present case, the heating rate of both water and alcohol was same. So same amount of heat was supplied, at any given point of time. However, water took more time to reach the temperature of 50 oC. This clearly depicts that, more amount of heat was supplied to water, as compared to alcohol, to reach the desired temperature. It also suggest that, water takes longer to change its temperature than the alcohol

Answer 2:
Correct option: For the same temperature change, water requires more energy

Reason:
In the present case, time required for water to achieved the same temperature as that of alcohol, at a constant heating rate, was more. This suggest that for the same temperature change, water requires more energy. This can be attributed to the fact that, hydrogen bonding in water is more stronger than that in alcohol. Due to this, more amount of energy is required to overcome hydrogen-bonding in water.
