Why can gases and liquids both transmit heat by convection?

Physics
1 answer:
Firlakuza [10]3 years ago
5 0
Basically, the temperature is a result of the average kinetic energy of all the atoms comprising the solid/liquid/gas. In solid, these atoms can just vibrate in place, leaving them to only be able to conduct and radiate heat. However, as you probably know liquids and solids take the shape of their container because the bonds between atoms are loose enough to allow them to freely move around. Due to each individual atom having its own energy, and these atoms being free to move about the liquid/gas they collide with other atoms in the substance. These collisions result in a transfer of energy. Finally, lower energy atoms "sink" and higher energy atoms "rise" thus creating a "convection current".

7 types of electromagnetic waves from lowest to highest frequency
goldfiish [28.3K]

Answer:

radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Explanation:

Electromagnetic waves are the waves which are created as the result of the electrical waves which are perpendicular to each other and also perpendicular to the direction of propagation.

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:  

<u>radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays</u>.

How does speed affect momentum
Arada [10]
Momentum = mass • velocity
M = m • v

Speed is a scalar quantity
Velocity is a vector quantity

That is truly the only difference
