Thermocouple thermometer
Mercury in glass laboratory thermometer
Mercury in glass clinical thermometer
|
| 2 |
A thermometer has a narrow capillary tube so that it. |
Gives alarge chagne for a given temperture rise
Quickly responds to temperature changes
Can read the maximum temperature
Can measure a large range of temperature.
|
| 3 |
Water is not a used as a thermometric liquid mainly due to. |
Non linear expansion
Clourless
Low boiling point (100 oC)
A bad conductor of heat
|
| 4 |
One disadvantage of using alcohol in a liquid in glass therometer. |
It wets the glass tube
It has large expansivity
It has low freezign point (-112 oC)
Its expansion is linear
