It's because of the gravitational forces
Answer:
CaCl2=1
KCl=3
Explanation:
CaCl2 has a very high heat of solution hence it is best at melting ice. It is better than all the other salts mentioned. Its dissolution in water produces a lot of heat which melts the ice.
A mixture of oil and water is:
Heterogeneous
immiscible
<h3>What type of mixture of oil and water is?</h3>
The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.
Thus, correct options are Heterogeneous and immiscible.

Precise and Accurate mean the same thing. I would consider measuring more than once to get a precise or accurate measurement.
1. Heart
2. Circulatory system
3. The circulatory system delivers oxygen and nutrients to cells and take away water .
4. Your heart is a muscle and it’s job is to pump blood throughout your circulatory system.
Hope this helps :)
