temperature of water. :) and youre welcome(:
Temperature of water.
ice cube,dice,child's block set,sugar cube
Both are made of many small particles that have been bonded together.
The length of a sugar cube.
depends on the two objects!
Suppose Y is a variable which is dependent on another variable X. Then the units used for the rate of change in Y, with respect to X, will be the units of Y divided by the units of X. For example, if x is the length of a side of a cube (in cm), and Y is its volume (in cm3), then the rate of change of Y, with respect to X, is measures in cm3/cm.
Dissolving dissolving! Watch your grammar. The best example is sugar cube dissolving in a water. Best way to dissolve it is to smash it, put it in water and then stir it.
Sugar's dissolveable qualities.
The process of a sugar cube dissolving in water is an example of physical weathering, specifically dissolution. The water breaks down the sugar cube into its individual molecules, resulting in its disappearance.
No, the dissolving of a sugar cube is a physical change, not a chemical change. The sugar molecules are still the same chemically; they are just dispersed in water instead of being in a solid form.
The air bubbles are trapped within the sugar cube and are released as the sugar dissolves in water. These air pockets are a result of the manufacturing process of the sugar cube, where they can get trapped during the compression of the sugar granules.
yes
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
Higher temperatures mean the molecules are moving more rapidly. This will speed up the process of disolving a sugar cube, because there is more activity.
The dependent variable in this experiment is the time it takes for the ice cube to melt. The independent variable, or factor being tested, is the temperature of either 70 or 90 degrees. By measuring the time it takes for the ice cube to melt at each temperature, you can determine whether it melts faster at 70 or 90 degrees.
This is a physical change the chemical composition of the sugar does not change
Yes, the "passive moving" of water across the membrane is considered osmosis.
The sugar cube will dissolve in the warm water as it is soluble. Stirring will help to speed up the dissolving process by increasing the contact between the water and the sugar cube. Eventually, the sugar will completely dissolve in the water, resulting in a sweet solution.
