Question

I already tried to do this with two thermometers but it's not working, so if anyone has the results to this lab please help me out, thank you! Pour about 1/2 cup of hot water (from the kitchen faucet) into a Styrofoam cup (A regular coffee cup can be used if you don't have a Styrofoam cup.). Very quickly, start the stopwatch and use your thermometer to measure the temperature of the hot water in degrees Celsius/Fahrenheit. Now add three ice cubes to the water and take the temperature every 30 seconds for 5 minutes. You can gently stir the water with the thermometer between recording times.

Answer 1

Record your data in the table below. Include a copy of the table with your assignment.

Answer 2

@Mertsj can you help me?

Answer 3

I have no idea what you are supposed to do.

Answer 4

@Mertsj I basically need to get a cup put some warm water in it, measure it, then put ice cubes it, and measure it at intervals of 30 seconds for 5 minutes. I tried to do this but my thermometers weren't working because the water is too cold to measure the temperature.

Answer 5

Then don't put in so much ice.

Answer 6

Try starting with boiling water. Then, hopefully, your thermometer will be able to register some change at least somewhat. Teacher won't mind if you start with a higher temperature if you explain your thermometer problem.

Answer 7

@physicsmama I tried that, the water was too hot for the thermometer. It wouldn't take the temperature it just kept flashing the leter "H" because it was too hot. When I put the ice cubes in it it flashed "L" because it was too cold. :/ So I don't know what to do.

Answer 9

What is the high and low limits of your thermometer?

Answer 10

bother. You'll have to go with less ice.

Answer 11

Good question Mertsj. You could try just adding one ice cube.

Answer 12

The high limit is 108 and the low limit is 95.

Answer 13

Start with hot water, let it cool until it feels very hot to your skin. Check the temp once in a while and wait until the thermometer stops flashing 'H' at you. Record that temp as zero, then add one tiny ice cube and take a couple more measurements. Even if you get only three or four you should have enough to draw a graph.

Answer 14

thank you!!

Answer 15

The other alternative is to ask the teacher if you can go in early and use the thermometer from the lab, or ask if you can borrow it overnight. Do you by any chance have a thermometer in your freezer? You know a portable one? That would work too.

Answer 16

I go to virtual school, and okay I'll see if we have a thermometer in our freezer
