Chapter 2, Problem 3AC
Summary Introduction
To explain:
Artificial ice cubes made of granite can be cooled in the freezer and used in drinks. Would these cool drinks more or less effective than an equal weight of ice cubes from the same freezer.
Introduction:
Absorption and retention of heat by any substance depends on the chemical structure of that substance, mainly on the type of
Hydrogen bonds are weak bonds that are more temperature to temperature. They absorb heat fast as well as release heat faster.

A group of students designed an experiment to determine the impact of sucrose concentration on the weight of potato cubes. The pieces of potato were initially the same weight, shape, and size. Each potato piece was submerged into a beaker containing one of the sucrose concentrations for 30 minutes. The final weight of the potato was measured and recorded in the table.
Which TWO conclusions can be correctly drawn from this data?
A
In the 0.4 mol/dm3 solution, the sucrose molecules moved across the semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration (the sucrose solution), leading to a decrease in the weight of the potato.
B
In the 1 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato.
C
In the 0.8 mol/dm3 solution, the sucrose molecules moved…

As with using the metric system, it is important in the sciences to learn to use and report temperature readings using the Celsius scale since it is more universally used than the Fanrenniore scale. The formulas used to convert between these two temperature scales are listed below.

Why is this important? How would the success of the experiment be affected if the wash solvent were warm? The purity of the substance would decrease with a warm wash.
