We are asked to calculate the temperature outside.
Calculate the volumes of the balloon:
Calculate T1 in K:
T1 = 19.0 °C +273.15 = 292.15 K
In an air-conditioned room at 19.0 C, a spherical balloon had a diameter of 50.0 cm. When taken outside on a hot summer day, the balloon expanded to 51.0 cm in diameter. What was the temperature outside? Assume that the balloon is a perfect sphere and that the pressure and number of moles of air molecules remains the same.
