Which of the following is a chemical property? freezing point color ability to react with oxygen hardness

Option (c) is the correct answer.

Explanation:

A property which does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

And, a property that changes chemical composition of a substance is known as chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

Therefore, ability to react with oxygen also depicts its chemical property.

Thus, we can conclude that out of the given options ability to react with oxygen is a chemical property.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
