superconductors
Superconductivity.
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
A superconductor. So far, it has only been possible to produce superconductors that work at extremely cold temperatures.
Metals heat up as electrical currents flow through them. Cold resistance is the metals resistance before it is operating. Hot resistance is the metals resistance after operating time has elapsed some.
Cold temperatures increase air pressure.
Superconductivity.
The resistance value for linear resistance is changed by changing the wavelength of the current or by installing additional resistors in the circuit. This restricts the amount of electricity which flows through the wiring.The resistance value for the linear resistance can be changed through strain over time. It can also be changed by changes in temperatures, such as going from hot to cold.

Superconductors are materials that have very low or no resistance to the flow of electricity. These materials usually need to be very cold for this property to appear.
cold temperature
Yes, a ball typically loses air in the winter. This is because the cold temperatures cause the internal air to decrease, which makes the pressure of the ball decrease.
No. Cold and flu viruses are unaffected by cold or even freezing temperatures.
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
The tundra is the climate region known to have cold temperatures and low vegetation. The cold temperatures prevent the vegetation from growing.
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
No.
