A helium balloon containing

6 \text{ dm}^3

of gas at

27^\circ \text{C}

and 100 kPa was released into the atmosphere. As it rose, the temperature and pressure both decreased. Assuming the balloon did not burst, and its volume stayed the same, what was the pressure inside the balloon when the temperature in the atmosphere had fallen by

30^\circ \text{C}

? a. 60 kPa b. 70 kPa c. 90 kPa d. 95 kPa
