12. Measure the temperature of two unknown samples with your thermometer
13. Record both temperatures using the scale on the straw.
please help ive been stuck for about 1 hour and a half
No answer it Mrs.Sue i need help with this question!
what is the answer
12 is telling u to Measure the temperature and collect the unknown samples that u grab. 13 still working on that
i found out what the answer is. but thanks Ms.Sue your famous on jiskha!!!:3
just do 13 skip 12
To measure the temperature of the unknown samples using a thermometer and a straw, you can follow the steps below:
1. Make sure your thermometer is clean and free from any debris or moisture. Clean it with a soft cloth if necessary.
2. Check if your thermometer is properly calibrated and ready for use.
3. Prepare the two unknown samples. Ensure they are at room temperature and not too hot or cold.
4. Place the first sample under the thermometer. Hold the thermometer vertically and avoid touching the sides of the container to minimize heat transfer.
5. Observe the mercury or digital reading on the thermometer scale. Take note of the temperature.
6. Repeat the process with the second sample. Make sure to clean the thermometer between measurements to avoid cross-contamination.
7. Use the scale on the straw to record both temperatures. Position the straw next to the thermometer, aligning the zero mark on the straw with the base of the mercury or digital reading line on the thermometer.
8. Carefully read the scale on the straw and record the temperature for each sample.
9. It's important to keep in mind that the accuracy of the straw scale may vary depending on its design and calibration. If you need precise measurements, it is always recommended to use a calibrated and reliable thermometer.
10. After recording the temperatures, apply any necessary calculations or analyze the data according to your experiment or task requirements.
Remember to handle the thermometer and unknown samples with care to avoid accidents or contamination. Always follow any specific instructions provided with your specific thermometer model.
