Jenny measures the temperature inside a cave to be 10°C. The temperature outside the cave is about 30°C warmer. How does the kin

etic energy of the air molecules inside the cave compare to the kinetic energy of the air molecules outside the cave? The kinetic energy of the air molecules inside the cave is the kinetic energy of the air molecules outside the cave.

<h2>Answer:</h2>

<em><u>The kinetic energy of the air molecules in the cave is less than the kinetic energy of molecules outside the cave.</u></em>

<h3>Explanation:</h3>

The kinetic energy of any molecule is directly proportional to the temperature of the gas.

Temperature of a gas is the heat energy provided to the molecules. As the temperature energy increase the molecules of the gas will move fastly and collide with each other.

So we can know the kinetic energy of molecules in the gas by measuring its temperature.

Hence the temperature of the cave is less than outside, so the kinetic energy will also be low.

How would you explain why liquids solidify when they are cooled???
Ostrovityanka [42]
When liquids are subjected to lower temperatures, the kinetic energy of the molecules would decrease accordingly making them closer to each other and leading to a decrease in volume until the substance is solidified. Hope this answers the question.

How does amplitude affect the wavelength?<br>​
docker41 [41]

Answer:

Amplitude does not effect the wavelength in linear system.

Explanation:

Amplitude:

It is the measure of height from peak to trough.

Wavelength:

It is measure of length from peak to peak.

There is no relation between the amplitude and wavelength but if the system will no more linear then high amplitude can cause the distortion in wave if more frequencies are present. However frequency and wavelength can be related. The wave with higher frequency have shorter wavelength and vise versa.

Frequency:

It is the number of waves passing through a given point in a given time period. It is measure in Hz or s⁻¹
