Question

PHY
The distance between the fixed points
of a thermometer is 20 cm. If the level
of the mercury in it is 13 cm, the
temperature in Celsius scale is​

Answer 1

Explanation:

Let the temperature be measured between the upper point 100

o

C and lower point 0

o

C

a) Given the distance between upper and lower fixed points=80cm

i.e. 1cm=

80

100

o

C

=1.25

o

C

1cm corresponds to 1.25

o

C

Given that the mercury level rises to a height 10.4cm above the lower fixed point

∴temperature=10.4×1.25

o

C=13

o

C

The temperature on celsius scale corresponding to mercury level of height 10.4cm=13

o

C

b) From celsius to fahrenheit scale

9

f−32

=

5

C

f=

5

9C

+32

=

5

9×13

+32

=55.4℉

the temperature recorded on fahrengeit scale=55.4℉
