It changes from a liquid from to a solid.
I hope this helps!
Answer:
"Freezing point and ability to react with oxygen" are chemical properties
Explanation:
The change of liquid into solid is the freezing point. The melting point is more than the freezing point in certain cases of mixtures for certain organic compounds like fats. As soon as the mixture freezes it becomes solid and which results in change in the composition from the liquid and solid in this way the it drastically reduces the freezing point. The melting point gets higher due to the pressure. This happens due to the release of heat of which results in the rise of temperature to the freezing point
.Also the reaction of elements with oxygen which leads to formation of new substance is also an chemical property
Answer: B= Rusting ability
Explanation:
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
1. Boiling point: is a physical property as there is a change of state.
2. Rusting ability: is a chemical property as there is formation of new substances.
3. Melting point: is a physical property as there is a change of state.
4. Density: is a physical property as there is no formation of new substances.
the answer is The average kinetic energy of the surrounding air particles increases.

When heavy exercise results in too much acid in the human body, then "Lactic acid fermentation" occurs in our body. It is a metabolic process by which glucose and other six-carbon sugars <span>are converted into cellular energy and the metabolite </span>lactate, and we feel a lot of pain like burning muscles
Hope this helps!
