ABSTRACT

We were given a task to handle an experiment about water and concentration. The activity that

has been chosen for us to carry out is three layers tea. The main objective for this activity is to

study the effect of concentration, weight and temperature of solution towards its density. The

activity was handled by preparing the solution first which are sugar palm solution, evaporated

milk, ice cubes and tea water. The three layers of solution will formed then and the concept of

water density is applied. Instead of attractive in the term of texture, this water also good with its

taste.

tightly packed the particles are in one

substance . For example, when we add tea

water, ice cubes will float instead of sinkthrough the tea water. This is due to ice

cubes is less dense than water. The empty

spaces within the ice structure translates to

an expanded structure. Thus, ice takes up

more volume than the liquid water

molecules. However, for more denser liquid

which is evaporated milk will be below the

ice cubes and tea water. Settled at the

bottom is the palm sugar solution which has

the highest density due to highest

concentration. But how concentration relate

with density?

Higher concentration means more mass of

solute in the solution. And since solutes

overall add negligible increase in volume to

the solution, density increases. As we know

some water has been removed from the

evaporated milk and sugar has been added.

This increase the total mass of solute within

the solution. The same thing goes to palm

sugar. When we heat up the solid pal sugar it

will melt and form a very viscous solution.

The total mass of solute in the solution is the

highest as we add only a small amount of

water before we melt it. So, this make the

palm sugar solution has the highest

concentration.

We has added ice cube to make the water

colder and feel good to drink but the main

reason for adding water is to reduce the

temperature of solution. We added ice cubes

before we add the evaporated milk. Density

of tea water and evaporated milk is almost

similar which has only a slight differences.

So this might cause the two solutionmiscible. So as to increase the density of

evaporated milk, mixed it up with iced

cubes. The molecules of the evaporated milk

are packed more closely together and

making its density increase. Meanwhile, the

tea solution that we add later has higher

temperature where the molecules will move

away from each other and resulting lower in

density.

CONCLUSION

After doing this activity we found that the

density play the most important role inmaintaining the position of liquid within the

three layers tea. Some factors that affect

density are temperature and concentration.

Lastly, the higher the density of liquid, the

more it will sink below and otherwise.
