Measuring Temperature Using Mercury and Pasco Thermometers
Day 1 cont.: Copy “Precautions” and copy the following:
Do not sit during lab since you are using boiling water
Do not plug in hot plate until you are ready to use it. It heats very quickly
Use beaker holder when moving beaker off of hot plate
Do not let the thermometer bulb touch the bottom of the beaker while boilingSlide3
Measuring Temperature Using Mercury and Pasco Thermometers
Day 2: Post Lab Requirements:
Title a new section called “Sample Calculations”
Complete 1 sample calculation showing a conversion from °C to °F using your alcohol thermometer ice water value.
Complete 1 sample calculation showing a conversion from °F to °C using your digital thermometer boiling water value.
Use GFS to calculate the temperature
change/difference
between the
ice water (Column 1) and hot water(Column 3) values
you obtained for
both the alcohol and digital thermometers.
Use GFS to convert your temperature difference from part “c” into F
°
and C
°
respectively. Slide4
Post-Lab Requirements cont.
2. Create a new section called “Post Lab Analysis”
What are your measured values for ice water for both alcohol and digital thermometers?
Are your values similar between the alcohol and digital thermocouple thermometers? If not, why do you think so?
What are your measured values for boiling water for both alcohol and digital thermometers?
Are your measured values for boiling water similar between the alcohol and digital thermocouple thermometers? If not, why do you think so?
Which thermometer do you think was more accurate in its measurement? Why do you think so?
You should have noticed that the temperature reading on the digital thermometer “bounced around” as you were trying to record the temperature of the ice water and boiling water. This is called “fluctuation”. What do you think caused this fluctuation?
Did your alcohol thermometer temps fluctuate? Why or why not?
Based on your answers to questions f and g has your opinion to your answer for question e changed? Why or why not
?
Based on the outcome of this lab what can you conclude about the accuracy and difference between alcohol versus digital thermocouple thermometers?
What did you like using better, the alcohol thermometer or the digital thermometer? Why?
