A sample of gas in a closed container of fixed volume is at $250 \mathrm{~K}$ and $400 \mathrm{~mm}$ of Hg pressure. If the gas is heated to $375 \mathrm{~K}$, its pressure increases to $600 \mathrm{~mm}$ of $\mathrm{Hg}$. By what factor will be the average speed of the molecules increases? (a) $1.22$ (b) $1.50$ (c) $2.25$ (d) $2.00$
