Why does a hot air balloon rise?

Biology
1 answer:
alina1380 [7]4 years ago
5 0

Answer: Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air. A hot air balloon uses a burner to heat up the air inside the balloon.

Hope this helps!!! Good luck!!! ;)

Are triglycerides dengerous
Hatshy [7]

They are not something that you prevent from being made in your body. They are automatically made when you eat food that is not automatically converted into calories. This is used for energy later on for you body.

But too much of triglycerides is bad for you. This condition is called hypertriglyceridemia. Your doctor can detect if you have this condition by simply running a lipid panel (a blood test) that measures your overall cholesterol, you LDL and HDL cholesterol, and also measuring your triglycerides.

If you do take this test, they will make you fast for about 8 hours. They make you do this because triglycerides are usually lowest after you fast but goes up really high after a big meal (like a Thanksgiving Dinner!).

(Extra: your triglycerides are measured in milligrams per deciliter (mg/dL) and if your levels are:

BELOW 150 -----------------Healthy

150-199 -----------------------Borderline

200-499 ---------------------High

500+ --------------------------Very High


Most people are under 200, so in the end, you don't have to worry about your triglyceride levels.
