Consider the graph below comparing the velocity distribution of the same molecule at three different temperatures (25°C, 50°C and 75°C). Identify which curve represents the gas at 50°C.
Consider the graph below comparing the velocity distribution of PH3 and Kr at the same temperature. Identify which curve represents a Kr.
Consider the graph below comparing the velocity distribution of the same molecule at different temperatures. Identify which curve represents a lower temperature.
Legend:
Curve A → blue
Curve B → red
