Question

HELP!!!!!!!


This experiment will demonstrate how the volume of water changes when it changes from liquid to solid state, or freezing.


The materials for this experiment are a large round balloon, water, marker, tape measure, and freezer.


our job is to observe the experiment and collect your own data from this demonstration. Start with a round water balloon filled with water.


Make sure that there is no air in the water balloon.

Draw a line around the equator, or center of the balloon.


Measure the circumference of the balloon where you drew the line with the tape measure.


The line around the balloon is measured with a tape, the results are 39.5 cm. Then put the balloon in the freezer for 24 hours, until it is completely frozen.


The balloon is now frozen, again measure the circumference of the balloon around the line you drew before.


The line around the balloon is now 41.2 cm.


Compare the circumference of the balloon before and after freezing. WHAT IS THE PERCENT INCREASE IN THIS MEASUREMENT?

Answer 1

Answer:  17%

Step-by-step explanation: Take away 39.5 cm from 41.2 cm and you get 1.7 then you move the decimal in till it turn into a percent and you have 17%.

Answer 2

The difference in the measurement is 1.7 cm and the percent increase is 4.30%

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

The line around the balloon is measured with tape, the results are 39.5 cm.

The line around the balloon is now 41.2 cm.

The difference = 41.2 - 39.5 = 1.7 cm

Percent increase = (1.7/39.5)×100 = 4.30%

Thus, the difference in the measurement is 1.7 cm and the percent increase is 4.30%
