Answer:
That there should be no distinction between a person of certain social standing than another form a different one. They all should be treated the same.
Explanation:
Unfortunately, this experiment showed the reality of today´s society: that eventhough racism, social distiction, bullying, is seen as wrong, it is still happening.
Social standing is very important in the bussiness world and service facilities. People still treat better some community or type of person because they think they are "better" for having something or its believes, it´s in their culture.
In this example, the priest had better service because society thinks that people church-related are better because of their values, type of life, etc.
However, the type of life some people have won´t have to matter when a service is provided. All arethe same.
Answer: A characteristic of matter that can be observed without changing the identity of the matter is a physical property.
Explanation:
A property that 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.
Whereas a property that changes chemical composition of a substance is known as chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
A chemical change cannot be reverted back.
Therefore, we can conclude that a characteristic of matter that can be observed without changing the identity of the matter is a physical property.
Weathering the process that breaks down exposed stone and rock causing it to split apart or wear away. Different forces can cause rocks to become weathered physical weathering is caused by purely mechanical changes to the rock while chemical weathering is caused by chemical reactions
The catastrophic resurfacing model suggests that planetary resurfacing on Venus occurred through infrequent, planet-wide volcanic events, large enough to bury all earlier material. In other words, resurfacing was a near-instantaneous change to Venus relative to the slow flow of geologic time.
