Question 3. What does a temperature difference of 10 on °C scale corresponding toon a Fahrenheit scale.

Solution:-

                           Δtc = 10              (:: Δ= d/dt)

We know     tf = 9/5tc + 32   ....................(0)

Applying Δ on both sides of equation (0),            

               Δtf  = 9/5Δtc   ....................(1)   

                                                                  (:: here 32 is zero because it is constant  

Put Δtc = 10  in equation (1)                     (:: Δ this use for differentiation 

Δtf  = 9/5(10)

Δtf = 18°F

*at any temperature difference in °C find by Δtf = 1.8(Δtc) equation

Question 1. The reading tA and tB of two centigrade scale thermometers A and B graded at ice point 0°C and steam point 100°C are related by the equation tA=l +mtB+n(tB)², where l, m,n are constants. When both are immersed in oil then thermometer A reads 51°C and thermometer B reads 50 °C. determine the reading on thermometer A when thermometer B reads 25°C? Comment on the question "which thermometer is correct".

Thermodynamics Question solution, Chapter1 Zeroth law of thermodynamics. Question 1. The reading tA and tB of two centigrade scale thermometers A and B graded at ice point 0°C and steam point 100°C are related by the equation tA=l +mtB+n(tB)², where l, m,n are constants. When both are immersed in oil then thermometer A reads 51°C and thermometer B reads 50 °C. determine the reading on thermometer A when thermometer B reads 25°C? Comment on the question "which thermometer is correct". Ans- tA=l+mtB+n(tB)² According to question tA=tB=0°C tA=l+mtB+n(tB)² 0=l+0+0 l=0 Second step tA=tB=100°C tA=l+mtB+n(tB)² 100=0+m×100+n(100)² m+100n=1             ----------------------------(1) For tA=51°C tB=50°C tA=l+mtB+n(tB)² 51=0+M50+n(50)² -----------------------------(2) Now using equation (1) and (2) find m&n 50m+2500n=51 50m+5000n=50 -        -             - ________________ 0      -2500n=1                  n=-1/2500 Put value of 'n' in equati

Question2. A new temperature scale N is to be defined. The boiling and freezing points of water on this scale are 100°N amd 400°N respectively. Then (a) what will be the reading on the new scale corresponding to 60°C? (b) At what temperature both the Celsius and new temperature scale reading would be same?
