Answer:
Explained
Explanation:
Metals are good conductors of electricity because they contain free electrons in their atoms. The outer shell of atom's of metal have free electrons. These free electrons are responsible of electrical conductivity of metals. These electron are not bounded by the attraction forces of the nucleous. They are free to wonder in lattice of positive ion and thus allow electrical conductivity.

Please see answer in explanation
Explanation:
1. Since each molecule has three kinetic degrees of freedom (can move in three independent directions), the gas must have 3N DoFs.
2. Each molecule has the three kinetic degrees of freedom the monotonic atom has moving without rotating but it can also spin. There are three axes for it to spin around so we would expect three rotational degrees of freedom, but as were as above, the one about the diatomic molecule's axis doesn't count because of quantum. So we have two rotational DoFs and three kinetic, for a total of 5 per molecules. So the gas will have 5N DoFs.
3.When a spring vibrates it has two DoFs, its KE and its PE, so adding 1 vibration adds 2 DoFs per molecule, giving 7 per molecule and giving thegas 7N DoFs.
It would take about 4.8 years to travel from earth to Saturn.
<h3>How long would it take?</h3>
We know that speed is expressed as the ratio of distance to time. In this case, we are trying to know ow many years would it take to reach the planet Saturn travelling at 21 thousand miles per hour.
Given that;
Speed = 21 thousand miles per hour
time taken = ???
Distance = 887 million miles
Speed = distance/time
speed * time = distance
time = distance/speed
time = 8.87 * 10^8 miles/2.1 * 10^4 miles per hour
time = 4.22 * 10^4 hours
If 8.766 * 10^3 hours make 1 year
4.22 * 10^4 hours make 4.22 * 10^4 hours * 1 year/8.766 * 10^3
= 4.8 years
