Microwave & Boiling Experiment
Aim of the Experiment:
To find out the amount of time water takes to cool
down to room temperature after being microwaved or boiled
Apparatus:
·
1
microwave
·
1
boiler
·
2
laboratory thermometers
·
Tap
water
·
1
microwaveable cup
·
1
measuring cup
·
2
stopwatches
Steps of Experiment:
1. From Experiment #1, amount of water to keep a
sponge moist is known.
2.
Fill
measuring cup with the amount of water.
3.
Pour
this amount of water in the microwaveable cup.
4.
Repeat
Steps 2 and 3 nine more times; thus, the total amount of times Steps 2 and 3
are repeated is 10. This is going along the fact that there would be 10 sponges
in each batch.
5.
Place
a thermometer in the microwaveable cup.
6.
Place
the microwaveable cup in the microwave.
7.
Repeat
Steps 2 and 3 ten times, this time with the amount of water going into the
boiler.
8.
Switch
on the microwave and boiler simultaneously, setting the timer on the microwave
according to the result determined in Experiment #2.
9.
For
microwave:
a.
When
timer ends, start the stopwatch.
b.
Take
the temperature of the water every 1 minute.
c.
Stop
the stopwatch when temperature stabilises.
10.
For
boiler:
a.
When
water is completely boiled, start the stopwatch.
b.
Open
the boiler.
c.
Place
a laboratory thermometer in the boiler.
d. Take
the temperature of the water every 1 minute.
e.
Stop
the stopwatch when the temperature stabilises.
11.
Repeat
Steps 1 to 10 for a second, confirmation experiment, and hopefully a third time
to be ensured of better accuracy of results.
12.
Collate
data.
