c. pyramidal
d. tetrahedral
Answer:
1. B Decantation. 2. D 3. B
Explanation:
This method is often used when dealing with mixtures of liquids or immiscible liquids with different densities
2. This is because the denser substance sinks to the bottom due to its higher density, while the less dense substance remains on the surface. It allows for the separation of the two substances based on their density.
3. The mixture is left undisturbed after the less dense substance has been poured off. This allows the denser substance to settle at the bottom while the lighter substance remains on top
4. It's a handy method for separating substances based on their density For example, if you have a mixture of oil and water, you can use decantation to separate the two. By letting the mixture sit undisturbed, the oil, being less dense, will float to the top, allowing you to carefully pour it off and separate it from the water.
Water has specific heat. This helps us with homeostasis.
