I think its a. i am not sure though.
Gases are more soluble in cooler solvents.
Hope this helps!
Answer:
The magnitude of charge on each sphere is .
Explanation:
Given that,
Force of repulsion between the charges, F = 22 mN
The distance between spheres, r = 16 mm = 0.016 m
It is mentioned that both the spheres carry equal charges. The force between charges is given by :
So, the magnitude of charge on each sphere is . Hence, this is the required solution.
Answer:
mass, volume: quantitative propereties: extensive properties
volume, melting point: quantitative propereties: intensive properties
Explanation:
The quantitative properties of matter are characteristics of matter that can be measured and of which quantities can be expressed.
Quantitative properties can be divided into 2 groups:
- Extensive properties: This is whose value depends on the amount of substance analyzed. They are not properties that allow us to distinguish one substance from another, since its value changes depending on the size of the object or sample that you have.
- Intensive properties: are those that do not depend on the mass or size of a body. That is, these are properties whose value is independent of the amount of substance analyzed; they are useful for differentiating substances.
On the other hand, the qualitative properties of matter are those that cannot be expressed in numerical values or quantities. They are detected, in many cases, through the senses, since they do not measure them.
In this case:
- <u><em>mass, volume: quantitative propereties: extensive properties</em></u>
- <u><em>volume, melting point: quantitative propereties: intensive properties</em></u>
What is it anyone answer it now
