Answer:
Explanation:
Most hypothesis involves the statement of a problem. It is one of the easiest way to explain results from experiments and a pool of observation.
To create a hypothesis about how soil acidity affects the growth of blueberries, we must bear in mind the follow:
The dependent variable is the growth of the blueberries.
The independent variables are the chemicals we might be adding to the soil to increase the acidity.
Our best hypothesis would be "how the addition of different pH of acid to soil affects the growth of blueberries".

Items of different densities can be separated by methods like the density column or using a liquid medium with a density in between the solids. High-density items sink, and low-density items float, enabling easy separation.
You can separate items of different densities by using a method called density column. This method involves stacking liquids of different densities on top of one another. For example, if you have oil and water, both liquids would not mix due to their different densities. Water has a higher density than oil, so oil will float on top of the water. You then could separate the two by carefully siphoning off the oil on top.
Similarly, if you have a mixture of solids with different densities, you can use a liquid medium that has a density between the two solids. The solid with the higher density will sink, whereas the solid with a lower density will float, allowing for easy separation.

b. Heat is transferred from the system to the surroundings in an endothermic
process.
c. The SI unit of specific heat capacity is calories per gram (cal/g).
d. Specific heat capacity is a positive value for liquids and a negative value for
solids.
e. The larger the heat capacity of an object, the more energy it takes it is to
cause a ten degree increase in temperature,
