A metal having a mass 29.94 g at 96.6 oC was placed in a coffee cup calorimeter of negligible heat capacity. The liquid in the calorimeter was 150 mL mercury at 17.7 oC, which specific heat is 0.140 J/g oC. Mercury density is 5.43 g/cm3. If the final temperature of the system was 33.3 oC, what would be the specific heat of that metal

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
