A very flexible heliumfilled balloon is released from the ground into the air at 20degree C The initial volume of the balloon is 5.00L , and the pressure is 760mmHg. . The balloon ascends to an altitude of 20Km , where the pressure is 76.0mmHg and the temperature is 50degree C What is the new volume,V2 , of the balloon in liters, assuming it doesn't break or leak? plss don't know how to solve this pls if you show me how to do it plsss. thank you
