Define the term temperature?
The degree of movement of heat from one place to another
The degree of heat intensity of a substance or body
The degree of coldness of a substance or body
The degree of intensity of a substance or body
The instrument used to measure temperature is called:
. a thermostat
a transistor
a thermometre
a tempo-metre
What is the outermost glass lens labelled ‘A’ on the thermometer called:
.stalk
stem
stylus
case
Identify the part labeled ‘B’ on the diagram
Bore
stem
bulb
scale
The part of a liquid-in-glass thermometer that houses mercury or alcohol, is called the:
stem
bore
bulb
basket
Temperature can be measured in:
o C, o F or K
o C, o F or o K
o C or o F
C, F or K
True or false, all thermometers have the same minimum and maximum limits
true
false
A major difference between the clinical thermometer and other liquid-in-glass thermometers is the _________________in the bore a little above the bulb.
constriction
contraction
consolidation
liquid
Which of the following thermometres shown in the photograph is best suited to provide: the current temperature, as well as the minimum and maximum temperatures within a 24 hour period?
A
B
C
Which of the thermometres shown in the photograph is used to accurately record body temperature?
W
X
Y
Z
What is the name of the thermometer used to measure body temperature?
calibrated thermometre
classical thermmetre
clinical thermometre
concise thermometre
What is the maximum limit of the thermometer used to measure body temperature?
100oC
42oC
98.6oC
37oC
Why is thermometer B not suitable for taking body temperature?
the minimum limit is too low
the maximum limit is too high
the liquid in the bore falls immediately when removed from the body part
the liquid in the bore does not respond to body heat
What is the function of the part labelled ‘C” on the diagram of the clinical thermometer?
prevents the quick back-flow of liquid into the bulb
allows for a slow rise of the liquid when heated
indicates the coolness of a substance
What is the name of the thermometer used to capture the current temperature, as well as the highest and lowest temperature within a 24-hour period?
laboratory thermometre
minimum-maximum thermometre
maximum-minimum thermometre
infrared thermometre
What is the minimum and maximum limits of a laboratory thermometer?
.0 – 100oC
1- 100oC
. 35 – 42oC
94 – 108oF
Name TWO materials commonly used inside a liquid-in-glass thermometer?
alcohol , silver
alcohol, mercury
silver, mercury
water and mercury
Thermometres functions on the principle that :
heat warms air causing it to rises, heat loss causes air to fall
materials expand when heated but contracts when cooled
materials change state when heated
heat travels very fast in narrow tubes
The alcohol used in, ‘liquid-in-glass’ thermometres is usually dyed/coloured to :
make it more effective in the bore
make it easily visible in the bore
comply with scientific regulations
True or false? The greater the kinetic energy of the particles within a body the higher the temperature of that body and visa-versa
true
false
