Question 1 (1 point) After a long day of studying their favorite subject, a student realizes that a muscle in
their back is quite strained. To fix the problem, they apply a hot water bottle. The
water bottle contains 575 grams of water at 80°C. The water eventually cools to
40°C. How many calories of heat could be transferred to the student's back?

i have a feeling this is a gay person trolling to make straights look bad.

i belive it is water

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
