superconductors
If a magnet is heated to a high temperature it will lose its magnetism.
A cooled liquid will become a solid.
The mercury lost all resistance and became a superconductor.
Gas
At the feezing point the liquid become a solid.Freezing is a physical change.
Super cooled metals are good conductors because their super cooled properties allow them to conduct electric currents without resistance. This means no loss of energy.
If a magnet is heated to a high temperature it will lose its magnetism.
shatter like glass
Superconductor
Because - anything cooled to absolute zero would no longer be liquid.
Yes,Mercury at 4kelvin is a super conductor it can be cooled down to that temperature.
well wetted round both conductors, and will appear shiny and smooth.
colder
Absolute zero is when the atoms of all matter will stop moving. It can't be further cooled once they stop.
A cooled liquid will become a solid.
A bose-einstein condensate.
