The freezing point and the boiling point of methane are − 295 ° F and − 263 ° F, respectively. The temperature at the surface of Titan, a moon of Saturn, is 93 K. If methane exists on the surface of Titan, it will be a _____.

Question

Quizplus · Accepted Answer

To determine the state of methane on Titan, we need to convert the temperature from Kelvin to Fahrenheit using the formula $F = \frac{9}{5}(K - 273) + 32$. Substituting 93 K into the formula gives $F = \frac{9}{5}(93 - 273) + 32 = -290$ °F. Since -290 °F is between the freezing point (-295 °F) and boiling point (-263 °F) of methane, it means methane would be a liquid on Titan.
