Ms. Moulden’s science class is learning to identify metals by their density. She gave the students a table, shown below, to help
identify their samples. One student’s sample has a volume of 12. 82 cm3 and a mass of 114.61 g. Calculate the density of the sample.
Using the table, what is the identity of the student’s sample?

Answer:
Water absorbs 84cal.
Explanation:
The given information about water is:
- mass of water (m): 12g
- change in temperature (ΔT): 7°C
With the given information, and the specific heat of water (c=1cal/g.°C), we can calculate the aeat that water absorbs, using the heat formula:
So, water absorbs 84cal.
