On a summer day early in the morning, a balloon is filled with helium when the temperature is 19°C, but the temperature will reach a peak of 42°C later in the day. The balloon holds 11.4 L of helium gas at a starting pressure of 239 kPa. The balloon will burst when the internal pressure reaches 256 kPa. Answer the following questions and show your work.

How many moles of helium gas are in the balloon?

What will the gas pressure be in the balloon at the peak temperature?

Will the balloon burst when the temperature reaches 42°C? Explain.
