"Lift" is pretty much defined as the difference in weight of equal volumes of the lifting gas (helium or hot air) and the ambient air. As a comparison, a typical density of air is about 0.00018 g/cm3. At the same temperature and pressure, air would be about 0.00128 g/cm3. The difference is 0.00128 - 0.00018 = 0.0011 g/cm3. So 1 cm3 of helium can lift about 0.0011 g. Scaling that up, 1 m3 of helium could lift about 1.1 kg. To achieve equal buoyancy, the air would have to be heated to about 1850 °C. Normal operating temperatures for hot air balloons are closer to 120 °C. At this temperature, the air density is about 0.00090 g/cm3, so the lift would be about 0.00128-0.0090 = 0.00038 g/cm3 so by comparison, helium would be 0.0011/0.00038 = 2.9 times the lift of hot air.

What is a sentence with heavier in it?
This fridge is much heavier than the microwave.I am heavier than a mouse.etc.
Both hydrogen gas and helium gas are lighter than air. Why is helium used to lift blimps instead of hydrogen?
Helium is non-flammable, making it safer than hydrogen which is highly flammable. This reduces the risk of fire accidents when using helium to lift blimps. Additionally, helium is more abundant and easy to obtain compared to hydrogen, making it a more practical choice for lifting gas.
Why is a grocery bag containing all canned goods is harder to lift than a grocery bag full of paper goods?
Canned goods are usually heavier than paper goods, resulting in a heavier overall weight for the bag of canned goods. This makes the bag harder to lift compared to a bag full of lighter paper goods. Additionally, the weight distribution of the canned goods may be more concentrated in one area, making it feel heavier to lift.
Why do most materials produce oxides rather than nitrides?
Most materials produce oxides rather than nitrides because oxygen is more abundant in the environment compared to nitrogen. Additionally, oxygen has a higher affinity towards most elements than nitrogen, making it easier for oxides to be formed. Lastly, oxides are more thermodynamically stable than nitrides under normal atmospheric conditions.
Is a magnet more dense than water?
No, a magnet is not more dense than water. Density is the measure of how much mass is contained in a given volume, and the density of water is greater than that of most metals, including magnets.

Paper.
Why are hydraulic lift tables better then normal lift tables?
Hydraulic Lift Tables Can Lift a Lot More Weight Than Regular Lift Tables. Also Hydraulic Lift Tables Are Much Safer Since the Fluid Provides Extra Rigidity to the Lifting Structure Versus Purely Mechanical Means.
Can a person lift more than his or her body weight?
yes
