Which 20.0 g sample of metal is most likely to undergo the smallest change in temperature upon absorption of 100.0 J of heat?
lina2011 [118]

Answer:

b. aluminum

Explanation:

The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.

Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.

Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:
