Why does heat take just seconds to damage your body, but cool takes minutes/hours to damage your body? | [
"Look at it like a phone and charger. If you put a load of energy into the phone (more than it's rated for), it'll do serious damage almost immediately. If you use an underrated charger, it'll put only a little energy in, but the phone will use more than it's getting and eventually die. Heat is just a form of ener... | [
"If it's hot enough to burn other parts of the body, it'll burn your mouth, too. In fact it'll probably burn your mouth easier than other parts of the body."

If you melt two identical candles at the same time, would they have the same appearance as they melted? | [
"Absolutely not. They'd have to be 100% identical (which they'll never be, since wax and wick have imperfections) and have to have 100% the same exact airflow and atmospheric content. Now if you *did* get conditions to be 100% the same, down to *every single individual atom* and *every single physical force* that ... | [

Why is Tuberculosis (TB) so frequently forewarned in many medicine advertisements? What makes TB such a large factor with certain medications? | [
"It is an infection that can lay dormant in many people without symptoms. Certain medications weaken the immune response allowing the TB to become an active infection. Once active, TB is very contagious and requires 6-9 months of multiple antibiotic treatments at least. One third of the world is infected with \"ina... | [

Why do we use AC current to get power to our homes, but most of our appliances use DC current? | [
