Temparature & Thermometer

Q.

The temperature of boiling water cannot be measured by a ______ thermometer.

Q.

What is the principle used in constructing any thermometer?

Q.

Which of the following instruments can be used to measure how hot the day is?

1. Odometer

2. Calorimeter

3. Thermometer

4. Barometer

Q.

Four arrangements to measure the temperature of the ice in a beaker with a laboratory thermometer are shown in Figures (a, b, c and d). Which one of them shows the correct arrangement for accurate measurement of temperature?

Q.

The temperature of boiling water cannot be measured by a ___ thermometer.

1. Clinical

2. Laboratory

3. Both the above

4. None of the Above

Q.

A clinical thermometer is

1. always mercury based

2. always digital

3. either mercury-based or digital

4. Neither mercury based nor digital

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. _____________ is a reliable measure of the degree of hotness or coldness of a body.

1. Fumes coming from the body
2. Color
3. Temperature
4. All of these

Q.

Why a laboratory thermometer is not able to record the temperature of the human body?

Q.

Kink is used in a clinical thermometer to:

1. Increase the temperature of thermometer.
2. Decrease the accuracy of measurement.
3. Ease the flow of mercury.
4. Restrict the backward flow of mercury.

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

Q.

Identify the type of thermometer shown below.

1. Max-min Thermometer

2. Can be both laboratory or clinical thermometer.

3. Laboratory Thermometer

4. Clinical Thermometer

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.
