If this relationship is direct, k = P/T. If it is inverse, k = P•T. Choose one of these formulas and calculate k for the pairs in your data table (divide or multiply the P and T values). Record the answers in the fourth column of the Data table. How constant were the values for k you obtained in Question 4? Good data may show some minor variation, but the values for k should be relatively constant. Comment on your calculated k values. Analysis Questions: What does temperature measure?

Measurements of a patient's temperature are routinely done several times a day in hospitalsDigital thermometers are used, and it is important to evaluate thermometers and select the best one. The accuracy of these thermometers is checked by immersing them in liquids of known temperature. Such liquids include an ice-water mixture at 0.0and boiling water at 100.0C at exactly 1 atmosphere pressure (boiling point with atmospheric pressureSuppose the data shown in the following table were obtained on three available thermometers and you were asked to choose the "best one of the three Which would you choose?

Use the data in the table to plot a heating curve of temperature versus time for a 180-g sample of water as it is heated at a constant rate from -20°C to 120°C. Draw a best-fit line through the points. Note the time required for water to pass through each segment of the graph. ( } Time and Temperature Data for Water Time Temp.

A team of students is collecting measurements of the boiling point of a liquid. The team determines a result of 37.0 + 0.5°C. Through research, the team finds that the accepted value of the boiling point of the liquid is 37.4°C. Which conclusion can the team draw from this result? The experiment appears to have uncovered a more accurato value of the boiling point. O It appears the data was collected accurately. OIt appears the data was collected inaccurately. The experiment should be continued until the team, with the exact result. Next Tet Satety course
