SOURCE: science question: If I dissolved some cocoa powder

If you dissolved cocoa powder in warm milk the cocoa particles, which are very tiny, will spread within the whole cup of milk because the milk is warm and the particles move a lot easier when heated. It will not be reversible since the cocoa particles are now spread within the whole volume of the milk and they will stay that way.
The same thing for question 2.

SOURCE: an experiment is being done to determine how light

Hi.
I see tests like evry now and again on here, and This one is one of the easier questions to answer.
In this problem, you are looking for the variable.
In that all 3 plants are the same size at the beginning, and that all 3 get watered the exact same amount at the same time, then the only variable is light.
You must determine is a direct, shaded on non-existent light source produces better growth of the zinnias.
The light source is the independent variable.

I hope this answer helps you out on your test!

SOURCE: -God exists even though I

You have every right to not believe in God. Once you die, and if there is life after death, you will then know if you were a fool or not for rejecting the existence of God. Personally I find it much harder to believe there is no God than to believe there is. The handiwork of a creator is all around us.

SOURCE: What is the difference between hot chocolate and cocoa powder?

Although the two names of drinks are used interchangeably, hot chocolate is a drink that's either made from real chocolate melted into milk or with packet hot chocolate powder. Cocoa powder is unsweetened and needs to be combined with sugar to create a sweeter drink.

In general hot chocolate is richer and sweeter than hot cocoa.

I have a project and i don't know what independent or dependent means


When conducting an experiment, a researcher usually has a dependent and independent variable. The independent variable is the variable that can be changed or manipulated (think of it as a cause). The dependent variable is the variable that depends on the independent variable (think effect).

For example, if you wanted to test whether practice improves an athlete's performance (lets say number of touchdowns):
  • Practicing (or not) is what you can manipulate. It is the independent variable.
  • Number of touchdowns is the dependent variable. The results depend on whether or not the athlete practiced.

Examples of independent and dependent variable


hi.

for a full definition, try wikipedia.
an independent variable can be freely changed.
a dependent variable will BE changed as the independent variable is changed
basically there are 2 main examples. mathematical, and experimental.

with experiments,(science, chemistry etc.) one example would be changing the amount of fertilizer fed to a plant to see how it affects growth. there are 2 variables here. amount of fertilizer used and growth of the plant.
the amount of the fertilizer can be freely changed. (independent variable)
the amount of growth DEPENDS on the amount of fertilizer (dependent variable)


with maths, you can use something like 2x+5=y.
x can freely changed. it is the independent variable. y will change depending on the value of x.

hope this helps
