Answer 1 Correct Option: <span>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, w</span>ater
takes longer to change its temperature than the alcohol<span> .......................................................................................................................
Answer 2: Correct option: </span> For the same temperature change, water requires more energy<span>
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 f</span>or 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.
<span>A compound which is called ionic compound dissociates
into ions when in aqueous solution. These ions move freely in the solution and
can allow the flow of electricity into the solution. These ions contains a certain charge or what is called the oxidation number.</span>
