Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Does the temperature of water affect the time it takes a sugar cube to dissolve? What is the IV (independent variable) in this experiment?
A
IV:Type of waterDV:Dissolving rate
B
IV:Temperature of waterDV:type of sugar cube
C
IV:Temperature of WaterDV:Dissolving Rate
D
IV:TimeDV:Number of sugar
Explanation: 

Detailed explanation-1: -Increasing the temperature of water, decreases the time it takes to dissolve the sugar in water. At a higher temperature, there are more spaces between the water molecules for the sugar to dissolve into so the solution forms more quickly.

Detailed explanation-2: -Independent variable: The time that is taken for all of the sugar to dissolve. This is the dependent variable. Dependent variable: If we use caster sugar or icing sugar, the type of sugar.

Detailed explanation-3: -The dependent variable is the amount of sugar dissolved. Constant factor is the amount of water.

Detailed explanation-4: -When water is heated, the molecules gain energy and move faster as they move faster. They come in contact with sugar. More often results in the dissolving faste p this. They suggest that when we increase the temperature, the dissolution rate of stuga in water increases.
