The document is solving a physics problem where a 3kg aluminum pot filled with 5kg of water is heated from 25°C to 95°C. It uses the specific heats of aluminum and water to calculate that the pot absorbs 1.65×106 Joules of heat to increase the temperature.

1. Question: A three-kilogram aluminum pot is f illed w ith f ive kilograms of w ater. How much heat is absorbed by the pot
and w ater when both are heated f rom 25°C to 95°C?
Answer: Using the table of specif ic heats, you can f ind the heat added to each item separately, and then combine
them to get the total heat added.
The total heat absorbed, therefore, must be 1.65×106 Joules.
