Question

The length of a mercury thread at a low fixed point and upper fixed point are 2cm and 8cm respectively for a certain liquid x. Given that the length of mercury thread at unknown temperature 0 is 6cm determine the volume of 0

Answer 1

Answer:

To calculate temperature, the quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcAT, where Q is the symbol for heat transfer, m is the mass of the substance, and AT is the change in temperature.

Answer 2

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

=55.4℉
the temperature recorded on fahrengeit scale=55.4℉
