Which of the following is NOT a true statement about liquids?
Nookie1986 [14]

Answer:

4

Explanation:

1 is correct

Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.

2 is correct

When the atmospheric temperature is increased, it also will increase the boiling point of the liquid

3 is correct

This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point

4 is incorrect

A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change

To see a RED object, all the light is absorbed except the Red and that is what we see as the color True False
Dafna11 [192]

Answer: True

Explanation:

Let's begin by explaining that the vision phenomenon depends on three elements: the observer, the object and the light source.

In addition, objects have pigments, which generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.  

In this sense, the colours we see are in fact the wavelengths that are reflected or transmitted from the object.  For example, a red object has that color because when it is illuminated whith white light, the pigments on this object abrsorb all the the wavelengths of the visible electromagnetic spectrum, except red. That is why red light is the only light that is reflected from the mentioned object.
