So its good to send it up when the outside temperature is hot?

Never mind. My next question in order to go up to the maximum potential, do you suggest the size of the balloon to be very big or large? What size would you say the ideal size that can achieve maximum height? Does it go up quicker if there is a more mass? Also I did not quite I understand you on your explanation about what type of temperature is good to reach the maximum height.

At what altitude will a trash bag filled with helium and tied at the bottom to stop leaking explode and fall back to earth? Can someone give me a rough estimate? Also, would it rise further up when the temperature is cold or when the temperature is hot? Thank you.
