Answer: The given statement is true.
Explanation:
When a substrate is exposed to one more more number of volatile substances that react together on the surface of substrate to produce a suitable deposit of a thin non-volatile film is known as chemical vapor deposition.
This type of reaction generally occurs in heat flux.
Therefore, we can conclude that the statement chemical vapor deposition can be defined as the interaction between a mixture of gases and the surface of a heated substrate, causing chemical decomposition of some of the gas constituents and formation of a solid film on the substrate, is true.
Answer:
C
Explanation
An object at rest will stay at rest.
The distance between Earth and Sun is about 0.0000038 times
the distance to the next nearest star.
(The next nearest star is about 265,300 times as far from us as
the sun is.)
The distance between Earth and Sun is about 0.000000000000000000068
times the distance to the next nearest galaxy.
(The next nearest galaxy is about 14,700,000,000,000,000,000 times
as far from us as the sun is.)
