11. Create a scale for your model thermometer. Divide the distance between the two
marks into 5-mm intervals. Starting with the lowest point, label the intervals on the
straw 0, 1, 2, 3, and so on. Describe your scale below.
12. Measure the temperature of two unknown samples with your thermometer.
13. Record both temperatures using the scale on the straw
Do you think your model accurately represents an alcohol thermometer? How is it like a manufactured
thermometer? How is it different?
How can you use the concepts of matter and the kinetic energy
of particles to explain the way your model works?
Approximately what Celsius temperatures do you think your
model measures? Explain your estimate.
Examine the structure and materials used in your model.
Propose a change that would improve the model. Explain your choice.
Please help
I need help cause it says "Measure Approximately what Celsius temperatures do you think your
model measures? Explain your estimate." but mine didnt work so what do i say?
11. To create a scale for the model thermometer, you will divide the distance between the two marks into 5-mm intervals. Starting from the lowest point on the straw, label each interval incrementally as 0, 1, 2, 3, and so on.
12. To measure the temperature of two unknown samples, place the model thermometer in contact with each sample separately.
13. Record the temperature of each sample by locating the position of the liquid level on the scale of the straw.
Regarding the accuracy of the model in representing an alcohol thermometer, it might have similarities and differences compared to a manufactured thermometer:
Similarities:
1. Both the model and manufactured thermometer use a liquid to measure temperature.
2. Both rely on the expansion and contraction of the liquid, as temperature changes, to indicate the corresponding temperature value.
3. Both have a scale that allows for measurement and recording of temperature readings.
Differences:
1. The model thermometer might not have the same level of accuracy and precision as a manufactured thermometer since it is created as a representation and might not be perfectly calibrated.
2. The materials used in the model thermometer might not be the same as those used in a manufactured thermometer.
3. The scale on the model thermometer might not be as finely calibrated as that on a manufactured thermometer, leading to potentially less precise temperature readings.
The way the model thermometer works is based on the concepts of matter and the kinetic energy of particles. When the temperature increases, the kinetic energy of the liquid particles also increases, causing them to move more vigorously. This increased movement results in expansion and a rise in the liquid level in the straw. Conversely, when the temperature decreases, the liquid particles' kinetic energy decreases, leading to contraction and a drop in the liquid level. By observing the position of the liquid level on the scale, the temperature can be determined.
Since the scale was divided into 5-mm intervals, the model thermometer can estimate temperatures based on the relative position of the liquid level. However, without knowing the specific properties of the liquid used and the precise calibration of the scale, it is challenging to estimate the temperatures accurately. It would be safer to regard the model thermometer as a qualitative representation rather than a quantitative measurement tool.
To improve the model thermometer, a few changes could be made:
1. Use a more reliable and accurate liquid with known temperature properties, such as using colored water instead of an unknown liquid.
2. Precisely calibrate the scale with the help of a reference thermometer to ensure accurate temperature readings.
3. Use a transparent or translucent material for the straw, allowing for clear visibility and easier reading of the liquid level.
These changes would enhance the reliability and usability of the model thermometer.
surely you can follow the instructions to draw a thermometer. google can provide you with many images to follow.
Then take a real thermometer and do step #12. Though I'm not sure how you would do this with your "model" thermometer.
google can help you with discussions on the other topics.
