Answer:
4.21778 J/(g*C)
Explanation:
specific heat = joules / (mass times temperature change)
949 / (9 times 25)
949 / 225 =
4.21778
Let's go through each of the answers and think about why they work or don't work.
Chemical forms compounds.
Nuclear changes the element completely. We're going to use the sun as an example. The sun is in a state of plasma. It's really hot and has all these particles hitting into each other. The nucleus' of atoms are hitting into each other forming larger elements. It's real crazy. Nuclear is not correct.
Physical cannot form a compound.
THen they would have a filled outer electron shell....and they would be negative with a -1 charge.....and be more likely to donate that electron to a metal to from a salt.
