A stoppered test tube traps $25\mathrm{.}0c{m}^3$ of air at a pressure of $1\mathrm{.}00$atm and

temperature of $18C.$ The cylindrically shaped stopper at the test tube's mouth has a

diameter of $1\mathrm{.}65cm$ and will "pop off' the test tube if a net upward force of $11\mathrm{.}0N$ is

applied to it$.$

Part A

To what temperature would one have to heat the trapped air in order to "pop off" the stopper? Assume the air surrounding the test tube is always at a pressure of $1\mathrm{.}00$ atm.
