Since filaments of iron wool are much thinner than an iron nail, they therefore have a much higher ratio of surface area to volume, and burning takes place at the surface, so the more surface, the more easily it burns.
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.
When a nail rusts, iron in the nail reacts with oxygen in the air to form iron oxide (rust), which has a greater mass than iron alone. As a result, the overall mass of the nail increases when it rusts because the mass of the iron in the nail combines with the mass of the oxygen in the air to form iron oxide.
The density of iron is higher than that of water, so the iron nail sinks in water due to gravity pulling it downwards. The weight of the iron nail is greater than the buoyant force acting on it from the water, causing it to sink.
The mass of a rusted nail is greater than that of an unrusted nail because rusting involves a chemical reaction between iron and oxygen in the presence of moisture, forming iron oxides (rust). During this process, oxygen from the air combines with the iron in the nail, effectively adding mass to the original nail. This increase in mass is a result of the incorporation of additional elements, which alters the overall weight of the nail.
An iron nail typically has a hardness of around 4 to 5 on the Mohs scale. Gypsum rates at about 2, while calcite is around 3. Therefore, since the iron nail is harder than gypsum and softer than calcite, it would likely rate closer to 4.
The wooden stool is heavier than the iron nail
Yes. But, compared to what? Better than lead but not as good as silver.
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.
Yes, the Babyliss hot roller set is better for your hair,for the iron can burn or damage your hair.
because iron doesn't burn...it melts.
The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.
A screw holds better than a nail.
The mass of a rusted nail can be greater than the mass of the nail before due to the formation of iron oxide (rust) on its surface. Iron oxide is heavier than iron, so the added weight contributes to the increase in mass. Additionally, the rust layer can trap moisture and other debris, further increasing the overall mass of the nail.

An iron nail is more strongly attracted to a magnet because the iron nail itself is made of ferromagnetic material, which can become magnetized in the presence of a magnetic field. This causes the iron nail to be attracted to the magnet.
When a nail rusts, it undergoes a chemical reaction with oxygen in the air to form iron oxide (rust). This process adds additional mass to the nail in the form of the iron oxide. Therefore, the mass of the rusted nail is greater than the mass of the nail before it rusted.
