If a balloon is heated what happens to the volume of the air in the balloon if the pressure is constant? Fri May 18 2012 · Best Answer: Under constant pressure : As temperature increases (balloon is heated) volume increases (balloon gets bigger). This is because heat causes molecules to move more quickly and spread out. This is also why you shouldn't stick a balloon under … If the volume of gas in the balloon remains constant then an increase in temperature would result in an increased gas pressure in a balloon . That result can be achieved in three ways: 1). Pump more gas into the balloon. or 2). Heat the balloon. or 3). With each heating and cooling cycle the pressure inside the balloon remains constant the volume of the balloon remains constant but there is this movement of air out of and back into the balloon . Gas expands with heat to the pressure inside the balloon will increase. For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. A. volume of the balloon increases B . gas pressure in the balloon increases C. average kinetic energy of the gas decreases D. all of the above For a balloon that is sealed and not ...
