Worksheet: Thermometry and Thermal Equilibrium
In this worksheet, we will practice defining temperature and measuring it according to different temperature scales.
Celsius and Fahrenheit temperature scales are convertible using the formula . Celsius and Kelvin temperature scales are convertible using the formula .
At what Celsius temperature do the Fahrenheit and Celsius scales have the same numerical value?
At what Kelvin temperature do the Fahrenheit and Kelvin scales have the same numerical value?
A person takes a reading of the temperature in a freezer using a thermometer and makes two mistakes while doing so. The first mistake is thinking that the sign of the reading is positive when it is in fact negative. The second mistake is thinking that the temperature scale used is Celsius when it is in fact Fahrenheit. The combined result of these two mistakes is that the person reads as , but it so happens that the Celsius temperature the person thinks that they have read is equal to the correct Fahrenheit temperature shown by the thermometer. What temperature does the thermometer actually read?
What is the most basic difference between a thermistor and a thermocouple?
- AA thermocouple requires a current source whereas a thermistor does not.
- BA thermistor requires a current souce whereas a thermocouple does not.
- CA thermocouple requires precise voltage measurements.
- DA thermocouple consists of two thermistors.
- EA thermistor is smaller than a thermocouple.
In 1701, the Danish astronomer Ole Rømer proposed a temperature scale with two fixed points, the freezing point of water at 7.5 degrees and the boiling point of water at 60.0 degrees. What is the boiling point on the Rømer scale of an oil that boils at a Celsius temperature of 300.0 degrees?
