What will happen to the telephone line if the temperature decreases in terms of the movement of the molecules?

In principle it should work better since the resistance falls as the temperature goes down.
In practice, if you have a dodgy phone line, a common reason is because the external jacket has deteriorated and allowed water in. So as cold weather often correlates to wet weather, it could get worse. This will have a much bigger impact than the temperature effects on resistance which are quite small.

What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
Does the movement of the particles increase or decrease wghile freezing?
The movement of particles decrease as temperature decreases, and vice versa. Therefore, they will decrease while freezing.
Which of the following methods of heat transfer involves the actual physical movement of high temperature molecules to region of low temperature?
"convection"
What happens to the movement of the molecules as the temperature rises from 0-100 degrees Celsius?
Their average increases by 36.6%
If you increase the temperature of a gas what happens to the movement of the molecules?
Their average kinetic energy, and hence their speed, increases.
What happens to the movement of molecules when their temperature is?
As the temperature is lowered, the movement of the molecules decreases.
What causes melting and boiling in terms of the kinetic molecular theory?
The kinetic theory states that when a solid is heated the bonds between the particles are loosened thus making it a liquid.
What happens when heat is removed from a liquid and its cools?
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
What happens to the molecules when temperatures decrease?
When temperatures decrease molecules slow down. When molecules speed up, temperature is increasing.
How does the movement of particles of matter change when temperature decreases?
Increases
Does the kinetic molecular theory need a temperature?
I would suppose so as without temperature there is no movement of molecules. That is what temperature is; the movement of molecules. Absolute zero in temperature would mean the complete stoppage of all molecular movement.
What happens to the various phases when the temperature is changed?
Say we start with a solid. The molecules vibrate around fixed points, little movement. When temperature rises, these molecules gain kinetic energy and spread out to form a liquid. The molecules are moving faster, colliding into each other every so often. Temperature rises again and the molecules reach the gas phase. The same when temperature decreases but just the opposite.
What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
What is the movement of atoms in a liquid during a temperature changes both increases and decreases?
As temperature increases, the atoms will move around more energetically - moving on average faster. Translational speeds increase, rotational speeds of the molecules increase, and the magnitude of vibrations of the atoms about their bonds in molecules increase As temperature decreases, the atoms move around less energetically - moving on average slower. Translational speeds decrease, rotational speeds of the molecules decrease, and the magnitude of vibrations of the atoms about their bonds in molecules decrease
What happens to gases when they are cooled?
The molecules of the gas will slowly start to slow down, causing a drop in temperature.
Does velocity of molecular movement decrease or increase with temperature?
The relationship between temperature and molecule movement is a direct variation. Whenever the molecule movement increases so does the temperature; when the molecule movement decreases so does the temperature. I hope that helps.
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
