What else can I help you with?
What has more density penny duck ping pong ball or water?
A penny
Rubber is heated what happens to it's density?
When rubber is heated, it typically expands and its density decreases. This is because the increased thermal energy causes the rubber molecules to vibrate more, creating more space between them and leading to a decrease in density.
Is a rubber ducky more dense then water?
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
What has more density a penny or a cork?
Usually, unless the cork is super compressed.
What substance is least dense rubber copper wood or mercury?
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
Is wood harder than rubber?
Yes, wood is harder than rubber. Wood is a natural material known for its density and durability, while rubber is a synthetic material that is much softer and more elastic in comparison.
Why does a penny sink faster in water than Sprite?
A penny sinks faster in water than in Sprite because water has a higher density than Sprite. The higher density of water creates more buoyant force, making it easier for the penny to sink through the liquid. Additionally, the viscosity of Sprite may offer more resistance to the penny's movement compared to water.
Which is more dense a penny from before 1972 or a penny from after 1972?
1972 has no significance in terms of changes in penny densities. The US Mint did not change the composition of its penny between 1909 to 1982, so any pennies from within this time period would have the same density. Pennies from this time period all contained the same proportions of metals (95% copper, 5% zinc.) Coins from post-switch 1982 to present day are minted of 97.5% zinc and 2.5% copper. Copper's density is ~8.9g/cm3 while zinc's density is ~7.1g/cm3. Considering the relative compositions of each version of the penny, the post-1982 penny would be the less dense penny, and the pre-1982 penny would be the more dense of the two.
What is the relative density rubber eraser?
Oh, dude, the relative density of a rubber eraser is basically how much denser it is compared to water. So, if you drop a rubber eraser in water and it sinks, it's denser than water. If it floats, it's less dense. It's like a little science party in your pencil case, man.
Rubber is unusual in that it shrinks when heated warming a rubber ball would?
Rubber's unique property is due to its elastic nature. When heated, the molecules in rubber become more active and move closer together, causing the rubber to contract or shrink. This is why heating a rubber ball would make it shrink instead of expanding like most materials.
Why do rubber bands sink?
The wonder and awe of observing that particular phenomenon has so far eluded me, but I can still state with some assurance that if a rubber band indeed sinks, then its density must be greater than the density of the fluid into which it has been placed.
Why gas particles diffuse more slowly through aluminum that through rubber?
Gas particles diffuse more slowly through aluminum than through rubber because aluminum has a higher density and more closely packed structure, which impedes the movement of gas particles. In contrast, rubber has a more porous and flexible structure that allows gas particles to move more freely and diffuse more quickly.
