A balloon has an internal pressure of 1.95 atm and a volume of 5.0 L. If the temperature where the balloon is released is 20 °C, what will happen to the volume when the balloon rises to an altitude where the pressure is 0.65 atm and the temperature is -15 °C? (Remeber to convert °C to °K)

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
