What has a greater density 20 kilograms of feathers 20 kilograms of balloons 20 kilograms of rock or 20 kilograms of plastic bottles?
Density = (mass) / (volume) Greater density corresponds to either greater mass in the same volume, or same mass in smaller volume. Any way you look at it, rock is the winner, over feathers, balloons, or plastic bottles.
Do ice and water have the same density?
no. Density of ice is more than of water...we can understand from ice sinking in water drinks... Edited by Dr.J. : How is it possible for the density of ice to be more (greater) than that of liquid water if ice FLOATS on lakes and rivers? Clearly, the density of ice is LESS than that of liquid water.
Why won't an ice cube float in alcohol?
Ice cubes typically float in water because ice is less dense than liquid water. However, some types of alcohol have a lower density than water, which means ice will sink in alcohol since it is denser than the alcohol.
Why doesn't a rock float?
A rock sinks in water because its density is greater than that of water. The weight of the rock is heavier than the water it displaces, causing it to sink rather than float.
Ice cubes float at the top of a glass of water What does this tell you about the density of ice compared to the density of water?
Ice is less dense than water because the molecules in ice are spaced out more, causing it to be less compact. This lower density allows ice to float on top of water, where it displaces an equivalent volume of water.
Which has greater density ice or water how can you say that?
Water has a greater density than ice.
Which has the greater density water or ice?
Water
Why does a ice cube fall in air?
B/c the density of the ice cube is greater than the density of the air.
Is the density of the inner Galilean satellites greater than the outer satellites?
Yes. The density of the Galilean moons decreases with increasing distance from the planet. This decrease in density is likely due to the higher ice-to-rock ratio in the farther moons.
When a rock is sinking in the water what dense does it have?
the rock has greater density than the water
What is the only substance that has a greater density as a liquid than a solid?
Water has higher density than ice. That is why ice floats on water.
Does the rock have lower density than a marble?
the rock has a greater volume than the marble
Do silicate rocks have greater or lesser density than moon and earths density?
Less than. The moon rock density is greater in ferromagnesion and nickel content, with greater density, whereas silicate rocks contain largely quartz and feldspar minerals.
Why can you lift a rock in water but a rock will not float?
In water, the buoyant force acting on the rock reduces its apparent weight, making it easier to lift. However, the rock is still denser than water, so it will not float and will sink when you let go. Buoyancy only makes it easier to lift the rock in water, but it won't make the rock float.
If you have two rocks rock A and rock B Rock A is bigger but has the same mass as rock B How will the density of the two rocks compare?
Since rock A is bigger but has the same mass as rock B, it will have a lower density compared to rock B. Density is calculated by dividing mass by volume, so the larger volume of rock A will result in a lower density.
How does the density of a rock affect its ability to float?
The density of a rock determines whether it sinks or floats in a liquid. If the density of the rock is greater than that of the liquid, it will sink. If the density of the rock is less than that of the liquid, it will float.
Mass of ice and rock?
The mass of ice is typically less dense than rock, so ice typically has a lower mass compared to an equal volume of rock. The exact mass of ice and rock would depend on the volume and density of each material.
