Calibrating Thermometers Quiz

What does calibrating a thermometer involve?

• Placing random marks on the thermometer

• Ensuring the thermometer is clean

• Putting the correct mark at the correct place

• Using the thermometer in boiling water

What happens if the thermometer is not calibrated correctly?

• It will give inaccurate temperature readings

• It will break easily

• It will not work at all

• It will show random temperatures

Which two points are used to calibrate a thermometer?

• Zero point and hundred point

• Freezing point and melting point

• Room temperature and boiling point

• Ice point and steam point

What is the temperature when the mercury length is 3 cm, given the distance between 0 and 100 degrees is 10 cm?

• 10 degrees Celsius

• 30 degrees Celsius

• 50 degrees Celsius

• 70 degrees Celsius

What is the significance of the ice point in thermometer calibration?

• It is irrelevant in calibration

• It is the freezing point of pure water

• It is used to mark 100 degrees Celsius

• It represents the boiling point of water

Why is it important to have two points marked on a thermometer?

• To allow for accurate temperature measurement

• To make the thermometer look symmetrical

• To ensure the thermometer is balanced

• To prevent the mercury from evaporating

How do you determine the temperature using a calibrated thermometer?

• Using a digital display

• By measuring the thermometer's weight

• Using a formula involving mercury lengths

• By guessing based on the mercury color

In the example, what is the room temperature if the mercury length is 6 cm, with L0 as 3 cm and L100 as 15 cm?

• 15 degrees Celsius

• 25 degrees Celsius

• 30 degrees Celsius

• 20 degrees Celsius

What is the formula used to calculate temperature in a calibrated thermometer?

• Theta = (Ltheta + L0) / (L100 + L0) * 100

• Theta = (Ltheta - L0) / (L100 - L0) * 100

• Theta = (L100 - L0) / (Ltheta - L0) * 100

• Theta = (L0 - Ltheta) / (L100 - Ltheta) * 100

If L0 is 2 cm and L100 is 20 cm, what is the temperature when Ltheta is 11 cm?

• 50 degrees Celsius

• 40 degrees Celsius

• 55 degrees Celsius

• 45 degrees Celsius
