No, steel is not lighter when in water. Steel is denser than water, so it will sink in water rather than float. The weight of the steel displaces an amount of water equal to its weight, making it sink.
No. You are lighter on the moon than on earth, though your mass remains unchanged.
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
Helium is lighter than air, so when it is trapped inside a balloon, it creates a lifting force known as buoyancy that causes the balloon to rise. This is because the buoyancy force exerted by the helium is greater than the weight of the balloon and the air it displaces.
No, carbon dioxide is heavier than helium. Carbon dioxide has a molecular weight of about 44 g/mol, while helium has a molecular weight of 4 g/mol. This means that helium is lighter than carbon dioxide and will rise above it in the presence of air.
You need more information.5 inch cube? Sphere? 5" thick of unspecified dimensions?What is the density of the Styrofoam? What is the thickness and density of the cardboard? (weight per square inch?).If you are creating something new, and wish to find a weight per square foot, per example, then you can probably get the required information on the WWW, or from your vendor.
Styrofoam generally provides better insulation than cardboard. Styrofoam has a higher insulating capacity due to its closed-cell structure, which traps air and provides better thermal resistance compared to the open-cell structure of cardboard. Additionally, Styrofoam is more water-resistant, making it a better choice for insulating against moisture.
No
Cardboard carton is stronger than styrofoam carton since it is used in most industrial packaging, whether it be the food industry or electronics industry. When it is sealed with a quality case sealer and a durable carton sealing tape, then you're sure that your carton packaging can withstand whatever environment it will be stored in.
weight of oil is lighter than water
Styrofoam is lighter than water, so it floats. In nature, heavy objects are more effected by gravity, so they are forced down.
The block of Styrofoam would float on the surface of the water because Styrofoam is less dense than water. Its buoyant force is greater than its weight, causing it to stay afloat.
Nitrogen is lighter than oxygen. The atomic weight of nitrogen is approximately 14, while the atomic weight of oxygen is approximately 16.
nobc the Styrofoam is heavyer than paper
Less expensive than solid wood, lighter weight to work with, lighter weight finished project, can be matched with other wood, easier to cut than some solid woods
The bag of stones is heavier because stones have a much higher density than styrofoam balls. Density is mass divided by volume, so the weight of the material is determined by the mass. Stones are denser and therefore heavier than styrofoam balls of the same volume.
heavier than a pencil but lighter than a book.
