Which of the following options correctly describe physical and chemical properties? A- A phase change always occurs when a physical property is measured B- When a chemical property is measured, the substance being observed is converted to a different substance or interacts with another substance. C- A chemical property of a substance can be observed without changing its composition or interacting with another substance. D- A physical property can be observed without a chemical reaction.

The correct options are B and D

Explanation:

A physical property is a property (of any substance) that can be observed without the substance undergoing any change in identity nor does it require a chemical reaction to determine. For example, colour and size are physical properties that are part of the identity of a substance and can/must be observed without a substance undergoing any change or chemical reaction. This explanation makes option A wrong and option D right.

A chemical property of a substance is the property that relies on the ability of that substance to undergo a chemical reaction/interaction with another substance to form a new/different substance. For example, ability of a substance to react with an acid (to form a different substance) is a chemical property. This explanation makes option C wrong and option B correct.

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
