Question
What will be the final temperature if 50 g of water at exactly $0{ }^{\circ} \mathrm{C}$ is added to 250 g of water at $90^{\circ} \mathrm{C}$ ?
Step 1
In this case, the heat gained by the colder water is equal to the heat lost by the hotter water. Mathematically, this can be represented as: \[Q_A + Q_B = 0\] Show more…
