Which of the following are characteristics of noble gases?

${ \bf{ \underbrace{Answer :}}}$

$\sf\red{B. \:They're\: inert.}$ ✅

An inert gas is one that does not undergo chemical reactions. The noble gases have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why they are said to be inert.

$\sf\purple{D.\: They \:don't \:react\: with\: other\: elements.}$ ✅

Noble gases are the least reactive of all elements. This is because they already have the desired eight total 's' and 'p' electrons in their outermost (highest) energy level.

A scientist reports a measurement of the temperature of the surface of a newly discovered planet as negative 20 Kelvin. What con

jarptica [38.1K]

Answer:

The temperature of this newly discovered planet violates the third law of thermodynamic, there is a mistake in this value.

Explanation:

The third law of the Thermodynamic says:

<u> At zero kelvin all molecular movement stops, which means that the entropy will be zero at this temperature.</u>

So we can say there is no thermodynamic system that has temperature values less than 0 K.

The conclusion of the report will be.

The temperature of this new planet violates the third law of thermodynamic, there is a mistake in this value.

I hope it helps you!

The resistance (R) of a copper wire varies directly as its length (L). Write this relation as a formula using k as the constant

Drupady [299]

Answer:

Explanation:

According to ohm's law current flowing in a conductor is directly proportional to the voltage applied across two end of conductor.

i.e. $V\propto R$

$V=R I$

where R=resistance

$R\propto L$

$R\propto \frac{1}{d^2}$

whee L and d are length and Diameter

thus $R=k \frac{L}{d^2}$

where k=constant of Variation
