I'm just wondering what a curve would look like if the x-axis is the temperature inside a hot air balloon and the y-axis is the diameter (in feet) of the balloon. There's a relation in how many pounds a hot air balloon can lift based on this curve and I'm looking to see what a good balance would be between both x and y to be able to lift 400 pounds into the air.(adsbygoogle = window.adsbygoogle || []).push({});
