Explanation:
The efficiency of a heat engine is defined as the ratio of the work output to the heat input into the system.
- It is highly impossible to get an engine that is 100% efficient.
- A heat engine that is 100% efficient suggests that all the heat input into the system is used to do work completely.
- There is no heat loss.
Efficiency = 
x 100
Efficiency has no unit

Answer:
The state of matter in Gas state has the greatest amount of particle movement.
Explanation:
Matter is classified generally in three states of matter and that is solid state, liquid state and gas state. So each state has its own properties and arrangement of atoms. If we consider solid state, the atoms will be bonded very close to each other and thus the movement of particles or atoms are very much restricted in a solid state. If we consider liquid state, then the atoms will be somewhat loosely bonded compared to solid and so the particles can be somewhat flexible to move from their original position. While for gaseous state, they are the most loosely connected state and so the atoms can move as freely as possible with no restrictions. Thus the gas state of matter has the greatest amount of particle movement among the given choices.

Answer:
D.
Explanation:
Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.
