Explanation:
Temperature affects the amount of sugar that will be dissolved in a liquid. It is general knowledge in chemistry that solutes tend to dissolve in hot solvents compared to cold solvents.
Hence, there is a positive relationship between dissolution of sugar in a liquid and increase in temperature.
To test this hypothesis, the variables are temperature and amount of solute. The volume of solvent and type of solvent must be held constant.
Different amounts of solute are dissolved in the same volume of solvent and heated to a constant temperature and the extent of dissolution of the sugar is observed for each experimental unit.
A control experiment is also set up in which different amount of sugar is dissolved in the same volume of solvent as above without heating and the results are compared.
The choice
which is the best name for these experiments would be Boyles' Law,
because it describes what will happen in the relationship between the pressure
and volume of the gas and Boyle’s Law is <span>is an experimental </span>gas law<span> <span>that describes how the </span></span>pressure<span> <span>of a </span></span>gas<span> <span>tends to increase as the </span></span>volume<span> of a gas decreases.</span> The correct answer between all the
choices given is the second choice or letter B. I am hoping that this answer
has satisfied your query about and it will be able to help you, and if you’d
like, feel free to ask another question.
Answer:
Polar covalent bond or just covalent bond
Explanation:
Thick lens will have shorter and consequently thin lens will have greater focal length. Because, For a thick lens, the optical path length of the light is more, than for a thin lens, thus, the bending of light will be more in case of a thicker lens. Consequently, it has a shorter focal length.
Answer:
± (.021 ) ohm
Explanation:
In the addition of two physical quantities , the uncertainties are simply added .
So , net uncertainty in the value of R will be
± (.007 +.014)
=± (.021 ) ohm
