Clinical Thermometer and Lab Thermometer

Q. Which of the following is used to measure body temperature?

1. Clinical thermometer
2. Laboratory thermometer
3. Indoor-outdoor thermometer
4. Max-Min thermometer

Q. You should take the reading with a laboratory thermometer when it is still immersed in the liquid you are measuring the temperature.

1. True
2. False

Q.

The clinical thermometer has graduations for a short-range.

1. ${35}^{o}C$to ${42}^{o}C$

2. $O^{o}C$to${100}^{o}C$

3. $273K$to $300K$

4. ${30}^{o}C$to ${37}^{o}C$

Q.

MODELING REAL LIFE The formula $K=C+273.15$ converts temperature from degree Celsius C to Kelvin K.

(c) Convert 300 kelvin to degree Celsius.

Q.

The bulb of the laboratory thermometer must be dipped properly and should touch the base of the container.

1. True
2. False

Q. Which of the following component of a mercury thermometer is responsible for keeping the level of mercury from falling suddenly?

1. Bulb
2. Scale
3. Capillary
4. Kink

Q. Which liquid metal is used for making thermometers?

1. Mercury
2. Iodine
3. Cadmium
4. Bromine

Q.

If there are 10 minor divisions between two major divisions, one major division representing $1^{\circ }C$, one minor division will be equal to

1. When the mercury level is in between the divisions

2. When the mercury level coincides with a minor division

3. When the mercury level coincides with a major division

4. Depends on the type of thermometer

Q. You should take a reading with a laboratory thermometer when__

1. It is still immersed in the liquid you are measuring temperature of.
2. It has been removed from the liquid you are measuring the temperature of.
3. None of these
4. Either a or b

Q.

Kink is used in some thermometers to ___

1. ease the flow of mercury

2. restrict the backward flow of mercury

3. None of the above

4. increase the accuracy of measurement

Q.

1. Can be both laboratory or clinical thermometer.

2. Max-min Thermometer

3. Laboratory Thermometer

4. Clinical Thermometer

Q.

Identify the type of thermometer shown below.

1. Can be both laboratory or clinical thermometer.

2. Max-min Thermometer

3. Laboratory Thermometer

4. Clinical Thermometer

Q. In a thermometer, there are $100$ major divisions between the freezing point and the boiling point of water. If each major division has $5$ minor divisions, what is the minimum reading that can be taken using the thermometer?

1. $1.2{}^{\circ }C$
2. $0.2{}^{\circ }C$
3. $1{}^{\circ }C$
4. $0.8{}^{\circ }C$

Q.

Mercury is used in thermometers to measure the temperature because:

1. It is the only metal that is liquid at room temperature.

2. It expands or contracts with temperature.

3. It changes state with change in temperature.

4. Mercury does not stick to glass walls.

Q. Why can’t we use a laboratory thermometer to measure the body temperature?

1. Its range does not include the body temperature range.
2. It is difficult to handle.
3. Laboratory thermometers do not have a digital display.
4. Because it does not have a kink.

Q. Clinical thermometers are always ______.

1. mercury based only
2. digital only
3. either mercury based or digital
4. coloured alcohol based
