Slower, at higher temperature that is.
hot water has fast moving particles, and cold water has slow moving particles
by convection and the particles go slower
In my experiment, he water with sugar had the most heat retention and cooled slower than the fresh water. I'm not 100% sure why, but I think it is because it is denser, therefore, when it is heated, more particles have been heated. If there are more particles heated, then it will take longer for each particle to cool down than water which has less particles.
It is Nickel. It is not harmful.

it contain gases cause of the minerals coming from the boiling water
Slower, the more water, the more time required to reach boiling temp.
Yes, because for example, cold water have less space between particles and they move slower than the hot water particles which are more far apart from each other.
It is Nickel. It is not harmful.
Yes
No. Salt makes the freezing point of water lower and the boiling point higher. The particles of salt get in the way of crystal formation when freezing. They also get in the way of particles trying to escape when boiling.
Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
