A faulty thermometer reads 5°C5 ° C in melting ice and 95°C95 ° C in steam. The correct temperature on absolute scale will be ______ KK when the faulty thermometer reads 41°C41 ° C.

Correct answer

0

Step-by-step solution

As per working of thermometers, X−LFPUFP−LFP=constant\dfrac{X - LFP}{UFP - LFP} = \text{constant}.

Therefore, we can write

41°−5°95°−5°=C−0°100°−0°\dfrac{41 ° - 5 °}{95 ° - 5 °} = \dfrac{C - 0 °}{100 ° - 0 °}

⇒C=3690×100=40°C=40+273K=313K⇒ C = \dfrac{36}{90} \times 100 = 40 ° C = 40 + 273K = 313K
