Substance AA Has Twice the Specific "Heat" as Substance BB Suppose We Put

Question 178

Multiple Choice

Substance AA has twice the specific "heat" as substance BB . Suppose we put 100g100-g blocks of these substances in direct sunlight. Assume both blocks are black and present the same surface area to the incoming sunlight. After a certain period of time, how are the temperature changes ΔTA\Delta T_{A} and ΔTB\Delta T_{B} of these blocks related (assuming they lose little heat to their surroundings) ?


A) ΔTA2ΔTB\Delta T_{A} \approx 2 \Delta T_{B}
B) ΔTAΔTB\Delta T_{A} \approx \Delta T_{B} , as both receive the same amount of energy
C) ΔTB2ΔTA\Delta T_{B} \approx 2 \Delta T_{A}
D) ΔTA=ΔTB=0\Delta T_{A}=\Delta T_{B}=0 , because neither receives any heat
