It is called the specific latent heat of fusion. C.
This is the heat change required in changing 1kg of a solid to its liquid and it occurs at the melting point. It is not associated with temperature change.
If it is to convert 1kg of liquid to vapor at its boiling point it is called the latent heat of vaporization.<span />
Answer:
So, according to Einstein's special relativity a person on Mars observe the light to be traveling at c = 3 x 10⁸ m/s.
Explanation:
The special theory of relativity has two main postulates:
1- <u>VALIDITY OF PHYSICAL LAWS</u>
The laws of physics such as Newton's Laws and Maxwell's Equations are valid in all inertial frame of references.
2- <u>CONSTANCY OF SPEED OF LIGHT</u>
The speed of light in vacuum is the same for all observers in uniform translational relative motion, and it is independent of the motion of the source or the observer. Thus, speed of light is a universal constant and its value is c = 3 x 10⁸ m/s.
<u>So, according to Einstein's special relativity a person on Mars observe the light to be traveling at c = 3 x 10⁸ m/s.</u>
Biome is an open system because energy and matter are constantly being transferred in and out.
i hope this helped you..
