Explanation:
Determine the density.
Explanation:
The best procedure a student can use to examine the intensive property of a rectangular block of wood is to determine its density.
An intensive property is a property of matter that is independent of the amount of matter present in it. Examples are density, melting point, boiling point etc.
Every substance in pure form have their distinct density. It is without regards to the mass and volume of such substance present.
Mass, length and volume are extensive properties that depends on amount of matter present.

The given question is incomplete. The complete question is as follows.
If more sugar were added to the solution on the left side of the tube, what would happen to the water level on the right side of the tube?
- There is more solute in the left arm of the tube than in the right arm of the tube.
- There is less free water in the right arm of the tube than in the left arm of the tube.
- Water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane.
- Solutes can pass through the selectively permeable membrane from right to left, but free water cannot.
Explanation:
It is known that when water is able to diffuse through a semi-permeable membrane from a region of high water concentration to low water concentration is called osmosis.
Since, more amount of solute is present on the right side of the tube so, there will be less amount of free water present over there as compared to the left side of the tube.
Also, water will be clustered around the hydrophilic solute molecules which is present on both sides of the membrane.
Thus, we can conclude that the true statements are as follows.
- There is less free water in the right arm of the tube than in the left arm of the tube.
- Water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane.
Answer:
not valid
Explanation:
Expert judgment is a useful validation method to verify the reliability of an investigation that is defined as “an informed opinion of people with experience in the subject, who are recognized by others as qualified experts in it, and who can give information, evidence, judgments and assessments ”
After submitting an instrument for comparison to the consultation and expert opinion, it must meet two quality criteria: validity and reliability. The validity of content is often established based on two situations, one that concerns the design of a test and the other, the validation of an instrument subject to translation and standardization procedures to adapt it to different cultural meanings. It is here that the task of the expert becomes a fundamental task to eliminate irrelevant aspects, incorporate those that are essential and / or modify those that require it.
