The graph shows a sample of gas when it is hot, cold, and at room temperature.

three graphs are plotted with number of particles on the y axis and energy on the x axis. all three graphs are smooth curves which rise up and then come down. the leftmost curve is the highest and is labeled a. the rightmost curve is labeled c and is the lowest. the curve in the middle is labeled b and has a height less than a and greater than c.

which statement is correct about curves b and c?

b represents hot gas and c represents gas at room temperature.
b represents gas at room temperature and c represents hot gas.
b represents gas at room temperature and c represents cold gas.
b represents cold gas and c represents gas at room temperature.
