Measuring Temperature

Question 1

Thermometers

Answer 1

A device used to measure temperature

Question 2

Thermocouple

Answer 2

Made of two different metals that are twisted together. When heated a small electrical current is generated. Measures very high temperatures but not low temperatures.

Question 3

Scales

Answer 3

A series of equally divided sections that are marked and numbered for use in measurement.

Question 4

Bimetallic strip

Answer 4

Made of two different metals joined firmly together. When heated one metal expands more than the other.

Question 5

Celsius scale

Answer 5

The most common scale for measuring temperature; on the Celsius scale, water at sea level boils at 100 degrees and freezes at below 0 degrees

Question 6

Thermograph

Answer 6

A bimetallic strip coils and uncoils as the temperature changes. One end of the strip is attached to a long, light metal lever that holds a special pen.

Question 7

Kelvin scale

Answer 7

A scale used for measuring temperatures in scientific experiments; on the Kelvin scale, pure water freezes at 273 K and boils at 373 K.

Question 8

4 devices for Measuring Temperature

Answer 8

Thermocouple
Bimetallic Strip
Recording Thermometer
Infrared Thermogram

Question 9

Absolute Zero

Answer 9

The coldest possible temperature is 0 K

Question 10

Sensor

Answer 10

A material that is affected by change in some feature of the environment, such as temperature

Question 11

Signal

Answer 11

Information about temperature, such as an electric current

Question 12

Responder

Answer 12

A pointer, light, or other mechanism that uses the signal in some way

Question 13

Infrared thermogram

Answer 13

Anything warmer than absolute zero gives off infrared radiation. Infrared radiation can be photographed with special films
