Answer:
Either the first one or the third one.
Explanation:
Using process of elimination: knowing that the controlled variable is something the conductor is able to control and stays the same throughout; the amount of water is the same, but it also states that temperature is not the same throughout. This cancels out B because the amount of sugar dissolved varies and doesn’t stay the same. D fits the same criteria as well.
so now we are left with A and C.
An independent variable is something that can be by itself and doesn’t depend on anything else. Sugar is NOT independent, as it dissolves DEPENDING on the amount of liquid. So we can already rule out that sugar is a dependent variable. Both A and C have those choices though, so now we are with the control group and the independent variable.
Think about it, which is the independent variable? Water amount doesn’t depend on anything, while the temperature depends on the room. So the answer is most likely A.
Hope this helps, don’t stress about homework. Happy Holidays!
In fluid dynamics, the wave height of a surface wave is the difference between the elevations of a crest and a neighbouring trough. Wave height is a term used by mariners, as well as in coastal, ocean and naval engineering.
A bond is a force of attraction between atoms as a result of transfer or sharing of electrons. Covalent bond is a bond between non metal atoms that results from sharing of electrons between the atoms. A single atom is formed when atoms share a pair of electron during formation of covalent bonds. Therefore, single covalent bonds exist in a molecule of carbon tetrachloride ( 4 single covalent bonds )
