Does cork expand when wet and how does this affect its properties and uses?
Yes, cork does expand when wet due to its porous nature. When cork absorbs water, it swells and becomes softer, which can affect its properties such as density and flexibility. This expansion can impact the effectiveness of cork in sealing applications, as well as its ability to provide insulation and cushioning.
Do the dry and wet iron filings show the same physical properties?
Dry iron filings and wet iron filings have different physical properties. Dry iron filings are free-flowing and easily spread out, while wet iron filings clump together due to the presence of water. Additionally, wet iron filings may rust more easily due to the moisture content.
A cork piece floats on water but an iron nail sinks give reason?
The cork piece floats because it is less dense than water, allowing it to displace enough water to support its weight. The iron nail sinks because it is denser than water and does not displace enough water to counteract its weight, causing it to sink.
A cork have a mass of 10g what is the density of the cork if the volume of a cork is 40cm3?
The density of the cork can be calculated by dividing its mass (10g) by its volume (40cm³). Thus, the density of the cork is 0.25 g/cm³.
Why does a wooden cork float in water but an iron nail sink?
Wooden cork is less dense than the water and the iron is not.
Why a wooden cork in water not an iron nail?
Because iron is rusting.
How are properties of cork and iron different?
Cork is lightweight, buoyant, and has insulating properties, while iron is dense, heavy, and a good conductor of heat and electricity. Cork is flexible, while iron is rigid. Cork is typically used in insulation, gaskets, and flooring, while iron is used in construction, machinery, and tools.

How are the properties of cork and iron different?
Whenever the sample masses are both on the same planet, 1 kg of anything has the same weight as 1 kg of anything else. Although the above answer is correct, 1 kg of cork would seem heavier because the weight is spread out. This makes it harder to balance, and would therefore require more energy.
