Why is it that when you heat up a small portion of mac n cheese, it gets warmed up quickly and soon burnt. I heated up my bowl because it was getting cold, only a little in it and it got started poping after 1 second. Why is this? another fun question, but for real, what does it mean?

well tbh it's just the microwave doing its job heating up your Mac n cheese. But while doing so the Mac n cheese absorbs a lot of heat and then releases it by popping.

I don't know

Explanation:

so true though

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.
