Answer:

Explanation:

When we say anything is a wave, what exactly do we mean? The most intuitive and straightforward wave to envision is a water wave. A motion, more specifically, is a disturbance that propagates or travels away from its source. Water waves are caused by a disruption in the water's surface, such as a rock tossed into a pond or a swimmer splashing the surface continuously. The noise for sound waves is a rise of air pressure, which may be caused by the oscillating cone within a speaker. There are many kinds of disturbances in earthquakes, including surface disturbances and pressure disturbances under the surface. Even radio signals are best deciphered by using a comparison of sea waves Water waves are helpful to visualize since they are more than just a mental picture. The amplitude, period, frequency, and energy of water waves are all the same as they are for all waves. A small set of underlying principles can be used to describe all wave characteristics.

Liquid water can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxy
soldier1979 [14.2K]

The temperatures of the gases will not be equal as oxygen gas will have a higher temperature than hydrogen gas because it has fewer moles overall.

<h3>Briefing :</h3>

The mechanical behavior of ideal gases is described by the ideal gas law. It has the ability to compute the volume of gases created or absorbed.

This equation is frequently used in chemical equations to convert between volumes and molar quantities.

According to the ideal gas law, there is a relationship between gas pressure, temperature, and volume.

PV = nRT

V is the same for both

So,

T is same for both.

When n increases, T decreases, so since n for hydrogen gas is 1 and n for oxygen gas is 0.5, it follows that oxygen gas will have a higher temperature than hydrogen gas because it has fewer moles overall.
