Does thickness of glass bulb affect sensitivity of thermometer?

A: The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. A smaller bulb contains less mercury and hence absorbs heat in shorter time. As a result it can response faster to temperature change.

How do you increase the sensitivity of a liquid in a glass thermometer?

There are some options:

1. Increase the size of the bulb.
2. Use thinner glass wall outside the capillary tube.
3. Decrease the size of the bulb.
4. Use narrower capillary tube.

What affects the sensitivity of a liquid in glass thermometer?

As sensitivity generally refers to the change in physical quantity (i.e. length of liquid column) per unit change in temperature, a greater bulb increases the sensitivity of a liquid in a glass thermometer.

Why does a thermometer have a large bulb?

Bulb thermometers rely on the simple principle that a liquid changes its volume relative to its temperature. In these cases, the change in volume is fairly small. All bulb thermometers use a fairly large bulb and a narrow tube to accentuate the change in volume.

Does bigger bulb increase sensitivity?

What factors affect the sensitivity of a thermometer?

Some of the factors which increase sensitivity are:

• Using a thermometer with a smaller glass bulb, as a smaller bulb contains less liquid and therefore, absorbs heat in a shorter time.
• Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube.

Does larger bulb increase sensitivity?

How do you increase the sensitivity of a light bulb?

Some of the factors which increase sensitivity are:

1. Using a thermometer with a smaller glass bulb, as a smaller bulb contains less liquid and therefore, absorbs heat in a shorter time.
2. Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube.

Which change increases the sensitivity of the thermometer?

The sensitivity of a thermometer can be increased by using a substance having a high coefficient of expansion and uniform expansion so that it expands with the slightest change in temperature.

Does larger bulb of thermometer increase sensitivity?

What affects the sensitivity of a thermometer?

The Sensitivity of Liquid Thermometers Using a narrow tube, as a small change in volume results in the liquid moving a larger distance along the tube. Using a glass bulb with a thinner wall, as heat can be transferred to the bulb more easily and a small change in temperature can be more easily detected.

Which modification will increase the sensitivity of the thermometer?

Sensitivity of Thermometer. Using a thermometer with a smaller bulb – A smaller bulb contains less mercury and hence absorbs heat in shorter time. A glass bulb with thinner wall – Heat can be transferred to the bulb easily. Capillary with narrow bore – produces a greater change in the length of the mercury column.
