Anything that happens to it but can be changed back to it's original form such as melting.(not rusting)
It either cleans the nail, or makes the nail have rust.
When heat is applied to an iron nail, the thermal energy causes the iron atoms to vibrate more rapidly, increasing their kinetic energy. As a result, the iron nail will expand due to the increased movement of the atoms. This expansion is a result of the increase in temperature causing the atoms to move further apart, leading to a temporary increase in the length of the nail.
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.
Like poles will repel.Unlike poles will attract.
physical changes~ cutting of paper, parked car, melting butter, flat basketball, and broken glass. chemical changes~burning gas, reacting iron with sulfur, vaporizing water.
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
physical or chemical
physical or chemical
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
physical
Heating is a physical change.
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
It is a physical change.
The chemical change of pizza, paper, and an iron nail would lead to a new substance(s) being formed with different properties than the original materials. A physical change, on the other hand, involves a change in the physical state or appearance of a substance without forming a new substance.
Preparation of pure iron from iron ores involve physical changes but also chemical changes.
