Question

The substances below are listed by increasing specific heat capacity value. Starting at 30.0 °C, they each absorb 100 kJ of thermal energy. Which one do you expect to increase in temperature the most? Silver, 0.239 J/(g °C) Aluminum, 0.921 J/(g °C) Lithium, 3.56 J/(g °C) Water, 4.184 J/(g °C)

Answer 1

Answer:

Silver, 0.239 J/(g °C)

Explanation:

• The heat change is related to specific heat as given by the formula;

Heat change = mass of substance × specific heat × change in temperature

• Therefore; considering same amount of substance or equal masses and have the same initial temperature.

• The change in temperature will be inversely proportional to the specific heat.
• Therefore; the higher the specific heat lower the temperature change.
• Hence,  the change in temperature will be highest for the substance with the lowest specific heat.

Therefore; the one that will increase in temperature the most is Silver
