Yes, you would add the two masses together.
Answer: Option (b) is the correct answer.
Explanation:
In solids, atoms are held together because of strong intermolecular forces of attraction between them.
As a result, solids have a definite shape and volume. Hence, its molecules are not able to slide past each other.
Whereas in liquids, molecules are together by less strong forces as compared to solids. Therefore, liquids do not have fixed shape and volume. They occupy the shape of a container in which they are kept together.
Therefore, molecules of a liquid are able to slide past each other.
In gases, molecules are held by weak Vander waal forces. So, they collide rapidly and occupy the volume of container and not the shape. Similarly, plasma is a hot ionized gas which consists of positive ions and negative electrons. Like gases, plasma also occupies the volume of a container.
Thus, we can conclude that liquid is the matter which can fill a container from top to bottom.
Hello,
I believe the answer is C. A and B say that it would help to change it but when we think about it data and opinions are not what people use to change a curriculum or program. Mainly they use surveys, which they didn't use here. Option D doesn't make any sense, data doesn't complement a program it supports some sort of theory which leads us to C. C is the only option where they use the data for effectiveness. Hope this helps!
I think it's called "<span>combustion." are there any answer choices though?

Condensation because condensation is a process of freezing
