Answer: Option (b) is the correct answer.

Explanation:

A process in which a fluid is heated then cold material (more dense) sinks at the bottom whereas hotter material (less dense) rises at the top is known as convection.

In convection, heat transfers from burner to the vessel and further it reaches to the fluid present into the vessel.

Therefore, we can conclude that the given situation represents convection as the kind of transfer of heat.

Why is creativity important in constructing scientific explanations?
poizon [28]

D. Sometimes it is necessary to put forth new theories to explain  experimental results,

Explanation:

Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.

Theories are explanation of scientific observations.

  • Most scientists are critical and creative thinkers.
  • They must be able to come up with a wide range of possible explanation to explain their findings.
  • The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
  • Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

1. Is O2 a compound? Explain.
zhuklara [117]
1. O2 is not a compound because it only contains one or more type of the same element atom.
2. O2 is a molecule because a molecule is one or more of the same element atom.
3. The law of conversion is that the mass of the system will stay the same when transfer takes place. Like if you had an equation O+H2—> H2O the mass will remain the same.

4. It will be equal to 10 because of law of conservation of matter.

5. One observation can be that the compound, reaction you’re observing, has change states.

My answer was 10 and it’s telling me it’s wrong..what did i do wrong?
Keith_Richards [23]

Answer:

1.586x10^-9

Explanation:

To make a multiplication in scientific notation we need to multiply the coefficients and sum the exponents:

Coefficients: 2.600 * 6.1000 = 15.86

Exponents: -5 + (-5) = -10

The result is:

15.86x10^-10

As the scientific notation must be given with only 1 number in the left of the point:

<h3>1.586x10^-9</h3>
