Answer 1

1) Cold is the lack of thermal energy. When an object emits heat, it cools down. It doesnt absorb some kind of cold energy

2) That substance would have a low specific heat. If the specific heat is high, it takes a lot more energy to raise its temperature. In the equation, q=mc(delta T), c(specific heat) is proportional to energy. If the specific heat is higher, the energy needed will be higher

3) You can only "measure" the heat of a substance through comparison with 2 different temperatures. Your hand will be the same temp as your forehead, so you can't tell if it's hot or not. You have to have someone with a more normal temp see if yours is hot or not

Answer 2

it may additionally be a controversy with the CMOS. attempt changing the lithium battery on the motherboard and spot if that makes a distinction. My computer became having themes with powering on some weeks in the past the place the skill change might specially circumstances no longer respond or it would activate yet supply some form of blunders and close off. I examined extraordinarily lots each and every element in my computer and it became out to easily be the battery on the motherboard. once I did that and reseated all my connections the element powered on and booted to the OS no problem. thinking how low-fee a CR2032 or some thing may well be while in comparison with a clean skill furnish, it would be rather worth attempting.
