Temperature Measurement | MCQs

Explanation

• Laboratory thermometers typically have a lower temperature range than clinical thermometers, and are designed to measure temperatures in a laboratory setting.
• The lowest temperature in a laboratory thermometer is often around -10°C or even lower, depending on the specific thermometer.

Explanation

When handling a clinical thermometer, you should:

• Wash it before use (to ensure cleanliness and accuracy)
• Stay at one place (to avoid moving around and potentially breaking the thermometer)
• Place it in a cover after use (to protect the thermometer from damage and contamination)

But you should not Run while handling a clinical thermometer, as this could cause the thermometer to break or become damaged.

Explanation

• Clinical thermometers, also known as medical thermometers.
• It typically have a narrow range of 35°C to 42°C.
• Which covers the normal body temperature range of humans (37°C ± 2°C).
• This allows for accurate measurements of body temperature in medical settings.

Explanation

• Laboratory thermometers typically have a range of 10°C to 110°C.
• It allowing for precise temperature measurements in a variety of laboratory settings.

Explanation

• The freezing point of water is 0°C (zero degrees Centigrade). 
• The boiling point of water is 100°C (one hundred degrees Centigrade).

Explanation

• The temperature range of the clinical thermometer is 94°F to 108°F.
• A clinical thermometer is a device that measures the temperature of the body.
• A mercury bulb is located at the end of a long, narrow glass tube.
• The average body temperature is 37° C, but it can range between 35 and 42° C.

Explanation

• The Fahrenheit scale has 180 divisions between the freezing point (32°F) and the boiling point (212°F) of water.
• This means that each degree Fahrenheit represents a temperature change of 1/180 of the range between the freezing and boiling points of water.

Explanation

In the Fahrenheit scale:

• The freezing point of water is 32°F
• The boiling point of water is 212°F

Explanation

There are three main scales used to measure temperature:

1. Celsius scale: Water freezes at 0°C and boils at 100°C.
2. Fahrenheit scale: Water freezes at 32°F and boils at 212°F.
3. Kelvin scale: Absolute zero (the theoretical minimum temperature) is 0K, and water freezes at 273.15K and boils at 373.15K.

Explanation

• A thermometer is typically made up of a glass tube filled with Mercury (Hg), a silvery-white liquid metal.
• The Mercury expands or contracts in response to changes in temperature, allowing us to measure the temperature.
