Why does the density of a substance remain the same for different amounts of the substance?

Answer:

Planet: The object orbits the sun

Not planet: The object is a satellite

Planet: The regions surrounding the object are free from debris

Not Planet: The object is triangular in shape.

Explanation:

A planet is characterized as:

Spheroidal (or at least big enough to be round-ish)

It should orbit the sun (not other planets, so satellites like the moon is not considered as a planet)

It should have no debris, or cleared of debris around its orbit

Although there is now the dwarf planet category, it satisfies almost all charateristics to be considered a planet, except the cleared of debris part.

Answer:

Planet: The object orbits the sun

Not planet: The object is a satellite

Planet: The regions surrounding the object are free from debris

Not Planet: The object is triangular in shape.

Answer:

For every temperature you use the formula given by the question.

at 3°C you have:

Reaction rate = (1000/0.2)/138.5 = 36 mg/L/sec

at 24°C you have:

Reaction rate = (1000/0.2)/34.2 = 146 mg/L/sec

at 40°C you have:

Reaction rate = (1000/0.2)/26.3 = 190 mg/L/sec

at 65°C you have:

Reaction rate = (1000/0.2)/14.2 = 352 mg/L/sec

As scientists work hard for the results, they may get biased and may sometimes come up with an answer that is based on that. In order to avoid such circumstances, scientific method is put into practice.

Explanation:

• Personal preferences can some times affect a scientific answer. That is not desirable as the experiments will be repeated by different individuals and the same results should be obtained.
• That leads to the importance of documentation of systemic observation, formation of hypothesis and the experimentation to confirm the results, which is the scientific way of coming up with the answer to a scientific problem.
• Scientific methods thus helps in bringing more credibility to findings of the scientists and can be repeated by others to obtain the same results.
