two pots with different amounts of water are heated by identical flames for several minutes. which one has the highest temperature? they have the same temperature. pot b pot a
Answer
Explanation:
Step1: Recall heat - mass - temperature relationship
The heat formula is $Q = mc\Delta T$, where $Q$ is heat, $m$ is mass, $c$ is specific - heat capacity (same for water in both pots), and $\Delta T$ is change in temperature. Identical flames mean equal heat input $Q$. Pot A has less water (less mass $m$).
Step2: Analyze temperature change
From $Q = mc\Delta T$, we can express $\Delta T=\frac{Q}{mc}$. Since $Q$ and $c$ are the same, and $m$ (mass of water in pot A) is smaller, $\Delta T$ for pot A is larger.
Answer:
Pot A
