To determine the specific heat capacity of copper, Alyssa performed an investigation by which she dropped a heated piece of copper into a calorimeter. Some of the data
Alyssa recorded is given in the following table.
copper
1049
98.9°C
Type of Metal
Mass of Metal
Initial Temperature of Metal
Mass of Water and Calorimeter
Mass of Empty Calorimeter
Initial Temperature of Water
Final Temperature of Water

33.5°C
a. What was the final temperature of the copper object? Explain your answer.
b. Determine the temperature change, A1, of the copper object? Show your work.
0
c. Determine the temperature change, At, of the water? Show your work
d. If the specific heat capacity of water is 4.19 J/g•°C, calculate the energy absorbed
by the water. Show your work.
For b, c, and d.

Type a, b, c, d in separate sections :)

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
