See which one answers the most trivia questions correctly.
You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance is less dense.
see if it floats, if it floats it is less dense.
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.
In science, "less dense" means that a substance has a lower mass per unit of volume compared to another substance. This is commonly observed when an object or material floats in a more dense substance, such as when ice (less dense) floats on water (more dense).
Density is measured and expressed as the mass to volume ratio. To determine what the density of a substance you measure its mass and divide that number by its measured volume (or you can look up the density based on what composes it). Then, using the same units, do the same for another substance. The substance with the larger number is more dense, has more mass per volume, than the substance with the lower number, and the same in reverse with respect to less density.
less
If more dense, it will sink when put into water; if less dense it floats.
the buoyant force
In general, hot means the substance is less dense. Less dense things tend to rise when they are in more dense things.
Gauge its buoyancy. Put it in the water. objects that are less dense will float while objects that are more dense sink.
The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
