There are two kinds of changes: physical and chemical. Physical properties can change without changing the substance, while chemical properties do change the substance.

Physical properties, like you said mass or texture, can change without changing the substance because the properties don't change the fundamental state of the subject; it doesn't change anything like atoms or molecules.

For example, when you freeze water to make ice, it's a physical change. The water goes from a liquid state to a solid state. But, the substance isn't changed: the compound is still H2O whether it's water or ice.

Another example would be cutting a cake. You make a physical change by cutting a slice out of the cake: you make it smaller. However, afterwards, the cake is still a cake. You didn't turn it into a pie or a muffin; it stayed the same thing, a cake, while just getting smaller.

Which of the following is true of intuitive decision making?

FrozenT [24]

The correct answer is E. It involves making decisions based on distilled experience. Something that is 'intuitive' is not rational, nor it comes from our conscious thought. It is not a complete emotion neither, it is more of a feeling that we have based on something that we saw or did, that belongs to the past experience. It is not necessarily slow, as it just emerges out of our subconsciousness.

sashaice [31]

Answer: c) simplified description or representation of reality.

Explanation:

Model is defined as the representation of any object, person or real-world component through its structure, illustration, form and description. It helps in enhancing the understanding of the entity through the formation of replica of that entity.

Other options are incorrect because fact, statistic ,observation or any other measurement unit does not describe the model that is representing any real world entity. Thus, the correct option is option(c).

However, he had always been thought to somewhat dimwitted. During the reign, if Caligula he developed a reputation for being an alcoholic. He did not have good experiences with women. He ended up getting married 4 times. This caused him a personal deterioration. At the end of his reign, he began losing trust in some of his affiliates.
