Question

Consider a substance that has high heat capacity. As compared to a substance with low heat capacity, when an equal amount of heat is applied to both, the high heat capacity substance will __________.
A. become more salty
B. turn to a liquid
C. become so viscous that it won't flow
D. explode
E. heat up much more slowly

Answer 1

If equal amount of heat is applied to both low heat capacity and high heat capacity substance than the high heat capacity substance will heat up much more slowly.

Answer: Option E

Explanation:

Heat capacity of substance denotes the heat required to increase the temperature of any 1 gram substance by 1 °C. So it is the ability of any substance to withhold the heat for longer duration or the heat required to break the bonds of the substance.

If a substance has high specific heat that means that substance require more amount of heat to break its bonds in order to change their state. And a substances with low heat capacity will easily get heated up.

So if same heat amount is applied to substances of high and low heat capacity simultaneously, the substance with low heat capacity will tend to get heated up faster. And thus the substances of increased heat capacity more slowly heat up.
