Thermometer (range, linearity and sensitivity) by Doni Saputra https://padlet.com/donisaputra/2nwtu4razd1vzhw8 Welcome to my Physics Class en-us 2022-02-08 01:03:33 UTC 2022-02-08 07:26:43 UTC hello@padlet.com donisaputra https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034385912 2022-02-08 01:14:43 UTC https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034385912 Question donisaputra https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034387665 Explain how the structure of a liquid in glass thermometer effects its sensitivity, range and linearity]]> 2022-02-08 01:16:00 UTC https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034387665 Answer by Christopher 9D: https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034819364 How does the structure of a liquid-in-glass thermometer affect:

Sensitivity:
More sensitive: 
-increased volume of bulb
-decreased diameter of tube 
-using alcohol(increases faster)

Less sensitive: 
-decreased volume of bulb 
-increased diameter of tube
-using mercury(increases slower)

Range:
Wider range: 
-decreased volume of bulb
-increased diameter of tube 
-using mercury(wider range between its melting point and boiling point)

Smaller range: 
-increased volume of bulb 
-decreased diameter of tube 
-using alcohol(smaller range between its melting point and boiling point)

Linearity:
Better linearity: 
-uniform tube diameter 
-using mercury(uniform expansion)]]> 2022-02-08 07:08:51 UTC https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034819364 Answer: by Calvin https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034821059 How to make the thermometer more sensitive:


You could increase the volume of bulb, so that when you heat the thermometer, more liquid will rise and get a greater reading. 

The second way is to decrease the diameter of the tube, because there is less volume to fill so there will be a larger rise which will cause a greater reading.

The third way is to use alcohol instead of mercury because alcohol expands more when compared to mercury.

How to make the thermometer show a wider range:

The first way is to decrease the volume of bulb.

The second is to increase the diameter of the tube.

And the third is to use mercury instead of alcohol.

How to make the thermometer show better linearity:

Make sure that the diameter of the tube is uniform.

The second is to use mercury instead of alcohol for more uniform expansion.

More sensitive:
-increase the volume of the bulb
-Decrease the diameter of the tube
-Use alcohol instead of mercury since alcohol expands more

Less sensitive:
-decrease the volume of the bulb
-increase the diameter of the tube
-Use mercury since it doesn’t expand as much

Range:
Wider range:
-Decrease the volume of bulb
-Increase the diameter of the tube
-Use mercury since it doesn’t expand as much

narrower range:
-increase the volume of the bulb
-Decrease the diameter of the tube
-Use alcohol instead of mercury since alcohol expands more

Better linearity:
-Make sure that the diameter of the tube is uniform
-Use mercury

When a thermometer has a larger volume, the more the liquid will expand and will be forced up and will get a greater rise. Can also use alcohol instead of mercury since it expands more.
When a thermometer has a smaller volume, it will be more sensitive, and the same volume of liquid that rise up with a bigger volume of thermometer, this will have a higher distance

Range:
Wider Range:
Can decrease the volume of the bulb or can increase the diameter of the tube


Linearity:
Better:
Needs a uniform tube diameter
Can use mercury]]> 2022-02-08 07:16:21 UTC https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034829204 gloria https://padlet.com/donisaputra/2nwtu4razd1vzhw8/wish/2034831214 senisitivity:
- alcohol expands more, so we use alcohol  rather than mercury 
- make the diameter of the tube smaller
- add more to the volume of the bulb

linearity: use the same tube diameter

wider range: decrease the volume
