Justify your answer by providing supporting evidence and an explanation of your answer.

Answer 1

Answer:

200 °C

Explanation:

Let’s convert all the temperatures to the same scale, say, Celsius.

Celsius

Water boils at 100 °C, so 200 °C is the temperature of superheated steam.

Fahrenheit

Water boils at 212 °F, so 200 °F is just below the boiling point of water.

$C = \frac{5 }{ 9}(F-32)$

$C = \frac{5 }{ 9}(200-32) = \frac{5 }{ 9}\times168 = 93 ^{\circ}\text{C}$

Kelvin

Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so

200 K is well below the melting point of ice.

C = K – 273.15

C = 200 -273.15 = -73 °C

Thus, 200 °C is the hottest temperature.
