two pots with different amounts of water are heated by identical flames for several minutes. which one absorbs the most thermal energy? pot a pot b they absorb the same amount of energy.
Answer
Explanation:
Step1: Recall heat - transfer formula
The heat energy $Q$ absorbed by a substance is given by $Q = mc\Delta T$, where $m$ is the mass, $c$ is the specific - heat capacity, and $\Delta T$ is the change in temperature. Here, the specific - heat capacity $c$ of water is the same for both pots, and assume the initial and final temperatures are the same for simplicity (since they are heated for the same time by identical flames). The mass of water in pot A is greater than that in pot B (as pot A has more water).
Step2: Analyze heat - absorption relationship
Since $Q = mc\Delta T$ and $c$ and $\Delta T$ are constant, and $m_A>m_B$ (mass of water in pot A is greater than in pot B), then $Q_A>Q_B$.
Answer:
Pot A
