Answer : Option B) All collisions between particles are perfectly elastic.
Explanation : Gases consits of molecules which are compressible because the gas particles which have a small volume compared to the container.
The collisions are perfectly elastic because when gases are left alone in a container they don't seem to lose energy and do not spontaneously get converted into a liquid, also energy is not lost during collisions.
In the diagram given above one can interpret that the gaseous molecules are in random motion inside the container and when they collide with other molecule of gas they do not lose energy. Therefore, this shows perfectly elastic collisions.
The answer is critical mass with no doub t
Answer:
uh
Explanation:
I think its like radar or something like that- im not too sure sorry
In a microwave oven, microwaves emitted by a small antenna are directed into the cooking compartment, and as they enter, they pass a set of turning metal fan blades.
it used to convey information from one place to another through intervening media,like- Radios and televisions
used in hospitals to produce photograph of bone to check for break or fracture.They can penetrate less dense matter such body tissue and skin.
The correct answer should be C. Melting because if energy such as thermal energy is supplied to a solid such as ice then it would melt
