Question

a faulty thermometer has lfp at 20 degrees and ufp at 100 degrees.using this thermometer the temperature of a body is found to be 36 degrees.what is the temperature on celcius scale​

Answer 1

Answer:

Correct option is

D

60

o

For two scales of temperature

100−0

C−0

=

UFP−LFP

Reading

−LFP

where LFP and UFP are lower and upper fixed points on the scale

∴

100

C

=

95−5

59−5

=

90

54

=0.6

⇒C=0.6×100=60

o
