Question

Three thermometers are in the same water bath. After thermal equilibrium is established, it is found that the Celsius thermometer reads 100°C, the Fahrenheit thermometer reads 212°F the Kelvin thermometer reads 273 K. Which one of the following statements is the most reasonable conclusion? a. The Kelvin thermometer is incorrect. b. The Celsius thermometer is incorrect. c. All three thermometers are incorrect. d. The three thermometers are at different temperatures. e. The Fahrenheit thermometer is incorrect.

Answer 1

Answer:

OPTION A, Kelvin Thermometer is Incorrect

Explanation:

Now, if you consider best two out of three results, then celsius and Fahrenheit thermometers read the same value, meaning both are right.

1) K = °C + 273

K = 100°C + 273

k = 373°C

Kelvin Thermometer is Incorrect

2) $C = \frac{F - 32}{1.8}$

when we have 212°F

$C = \frac{212 - 32}{1.8} \\\\= 100^\circ C$

which is correct
