Liquid in Glass Thermometer Quiz

What is the basic principle behind the operation of a liquid in glass thermometer?

• Liquids expand as temperature decreases.

• Liquids contract as temperature increases.

• Liquids expand as temperature increases.

• Liquids remain constant regardless of temperature.

Which of the following is an advantage of using mercury in thermometers?

• Mercury clings to the walls of the capillary tube.

• Mercury expands non-uniformly.

• Mercury is inexpensive.

• Mercury does not wet the walls of the capillary tube.

What is a disadvantage of using mercury in thermometers?

• Mercury is non-toxic.

• Mercury has a high freezing point.

• Mercury is a poor conductor of heat.

• Mercury is inexpensive.

Why is alcohol suitable for measuring low temperatures?

• Alcohol has a high boiling point.

• Alcohol has a low freezing point.

• Alcohol is opaque.

• Alcohol is expensive.

What is a disadvantage of using alcohol in thermometers?

• Alcohol does not cling to the walls of the capillary tube.

• Alcohol has a high boiling point.

• Alcohol is transparent and needs coloring.

• Alcohol is easily visible.

Which characteristic is important for a liquid used in thermometers?

• It should expand and contract rapidly over a wide range of temperatures.

• It should expand and contract slowly.

• It should be a poor conductor of heat.

• It should cling to the walls of the capillary tube.

What is one way to increase the sensitivity of a liquid in glass thermometer?

• Use a liquid that expands slowly.

• Use a larger mercury bulb.

• Use a smaller bore for the capillary tube.

• Use a thicker wall for the bulb.

How does a smaller bulb affect the sensitivity of a thermometer?

• It makes the thermometer less accurate.

• It decreases the response time to temperature changes.

• It increases the amount of mercury needed.

• It absorbs heat in a shorter time, increasing sensitivity.

What effect does a thinner wall have on a thermometer's sensitivity?

• It decreases the thermometer's accuracy.

• It makes the thermometer less sensitive.

• It increases the amount of liquid needed.

• It allows heat to transfer more easily, increasing sensitivity.

Why is a narrow bore beneficial for thermometer sensitivity?

• It makes the thermometer more expensive.

• It reduces the thermometer's accuracy.

• It produces a greater change in the length of the mercury column for small temperature changes.

• It decreases the length of the mercury column.
