58 questions· page 1 of 6
The temperature of a substance is measured with a liquid-in-glass thermometer.
Which physical property changes so that the temperature can be measured?
Options
A length of the thermometer
B mass of the liquid
C specific heat capacity of the liquid
D volume of the liquid
A liquid column in a liquid-in-glass thermometer is long at . The column expands by when heated to .
Measuring from P, how long is the liquid column at ?
Options
A
B
C
D
In many applications, a thermocouple is used to measure temperature instead of a liquid-in-glass thermometer.
Which property of a thermocouple is a major advantage?
Options
A its greater heat capacity
B its smaller temperature range
C its quicker response time
D it has a non-linear output
A liquid-in-glass thermometer consists of a bulb containing a liquid which expands into a thin capillary tube.
The liquid in the thermometer is replaced by the same volume of a different liquid that expands more for the same temperature rise. The length of the capillary tube remains the same.
How does the new thermometer compare with the old thermometer?
Options
A It has greater sensitivity and a greater range.
B It has greater sensitivity but a smaller range.
C It has the same sensitivity and the same range.
D It has the same sensitivity but a greater range.
The diagrams represent four thermometers.
Which thermometer has the greatest sensitivity and which thermometer has the greatest range?
Options
| greatest sensitivity | greatest range | |
|---|---|---|
| A | P | R |
| B | P | S |
| C | Q | R |
| D | Q | S |
The diagrams represent four thermometers.
Which thermometer has the greatest sensitivity and which thermometer has the greatest range?
Options
| greatest sensitivity | greatest range | |
|---|---|---|
| A | P | R |
| B | P | S |
| C | Q | R |
| D | Q | S |
The diagram shows a clinical thermometer.
Which factor affects the sensitivity of the thermometer?
Options
A the constriction
B the diameter of the bore
C the length of the glass tube
D the thickness of the glass tube
Which row is correct for a thermocouple thermometer?
Options
| measures very high temperatures | responds quickly to change in temperature | |
|---|---|---|
| A | no | no |
| B | no | yes |
| C | yes | no |
| D | yes | yes |
