Explanation:
Charles's law gives the relation between volume and the temperature of ideal gas when pressure is held fixed. It states that the volume of an ideal gas is directly proportional to its temperature at constant pressure.
If the temperature of an ideal gas is doubled, its volume also gets doubled as there is a direct relation between volume and temperature.
It is the time period where the commonly accepted theory of the earth being at the center of the solar system is switching over to the refused theory of the sun being at the center of the solar system.

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.
