Question

The initial and final temperatures of a water bath are (21.0+0.5) C and (42.5+0.5) C. What is the rise in temperature of the water bath and the greatest fractional error in the determination of the rise in temperature.       ​

Answer 1

Answer:

θ

1

=(40.6±0.2)

o

C,θ

2

=(78.3±0.3)

o

C

Rise in temperature, θ=θ

2

−θ

1

=78.3−40.6=37.7

o

C△θ=±(△θ+△θ

2

)=±(0.2+0.3)=0.5

o

C

Hence, rise in temperature = (37.7±0.5)

o

C
