Model Hot Air Balloons
How do I find the mass of air in a model hot air balloon?
Ok, I need to find the weight of the hot air in a model air balloon that I’ve constructed. The density is 1190 g/m3 and the volume of the balloon is 0.97m3.
Also, I need to determine the grams of unheated air displaced by my balloon. It weights 77.76g deflated.
Thank You.
Basically, I’ve got the weight of my deflated balloon, of which is 77.76g. I need to calculate the grams of unheated air displaced by my balloon, giving its volume(.97m3) and the density of air(1190g/m3). Then, I must determine my balloons total weight, and the weight of just the hot air in the balloon.
The temperature of the hot air is 21C and the room temperature is 22.5C.
Density= (Mass/Volume)
your second question has to be more clear. Im not sure what you are looking for or if you have sufficient information. I think you are looking for this: find the mass of it with air then subtract this from the mass deflated(77.76) to get the air.
