Scientists often work on projects for a long time and fail to see sources of error in their research. Which process allows an ou
prohojiy [21]

Answer:

The correct approach is Option B (Peer Review).

Explanation:

  • Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.
  • Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.

Other approaches do not apply to the example mentioned. Although the one mentioned is right.

Freezing point and boiling point of a substance P is -220 0 c and – 185 0c. A t which of the following range of the temperatures
Firlakuza [10]

Answer:

Between -195°C to -215°C

Explanation:

We begin from this data:

P under -220°C will be solid, because -220°C is the freezing point.

Above -220°C, P will be at liquid state.

Then -185°C is the boling point, so above that temperature we have P as a gas.

Between -175°C to -210°C

Above -185°C we said that P is gas, so at -175°C P is not liquid. This state is F.

Between – 190°C to -225°C

At -190°C, we can have P as liquid, but -225°C is under -220°C, where P changes from liquid to solid. Then, this state is also F.

Between -200°C to -160°C

Above -185°C we said that P is gas, so at -160°C P is not liquid. This state is also F. The same, as the first situation.

Between -195°C to -215°C

-195°C is a lower temperature than -185°C. P is still liquid, we did not get the boiling point yet. -215°C is higher than -220°C, P is also liquid. There are still 5°C until P completely freezes. <em>This is the correct choice.</em>
