A student scientist closes up an empty soda bottle and attaches a pressure gauge to the top. The initial room temperature is 20.7 °C and the bottle has a starting pressure of 0.98 atm. Ignoring safety advice about never putting lab equipment into the microwave, they throw it in and heat up the bottle for a minute. If the pressure gauge survives this risky experiment what do you predict the pressure will be, in atm, after the air inside is heated up to 80.4 °C? Don’t forget to convert all temperatures to Kelvin before doing any calculations.
