; μJ = a unit of energy) of various gases at different temperatures (in °C). Table 3 below lists the masses, in atomic mass units (amu), of the atoms making up the molecules of the gases.
37. Suppose that identical warm objects, each at 50℃, are immersed in equal volumes of each of the gases listed in Table 1. Assuming that the gases are initially at 20℃ and the same pressure, which of the gases will conduct the greatest amount of heat away from the object immersed in it in a given amount of time?
Answer and Explanation
Your Answer is
Correct Answer is A
Explanation
The higher the thermal conductivity, the more heat it conducts, so look at the column in table 1 where the temperature is 20 degrees, the highest thermal conductivity is CH4:334
