Presidential approval ratings essays

Presidential approval ratings essays Presidential approval ratings can either increase or decrease. It fluctuates by how well the people perceive the president is doing his job. If they like what they see, they are for the president. But, if times are tough, they use the president as the scapegoat for their problems. A) Presidential approval ratings decrease when negative events or moral decreasing events occur. The nation doesnt like to have a president who partakes in actions that hurt the character of the nation or the character of themselves. When incidence like that happen, the people start to evaluate the capabilities of the president. The president is seen as a figure head of our country and if they mess up, they are likely to have a decrease in approval. Nixon is a good example of a decrease in approval ratings. When the nation found out about his involvement in the Watergate scandal and his lying to the court, they quickly lost respect for him as a person and as a president. This helped force his resignation from the White House. Clinton was also involved in a scandal but his sexual relations didnt have anything in his running of the country, which was very good at the time. Even though he was going through legal battle, the country was still flourishing. Presidential approval ratings also decrease during times of economic hardship. When the country is doing bad, and people are losing money, prices are being inflated, or there is a rise of unemployment, the president is the person that everyone points their finger to. He is supposed to prevent economic hardship and when he cant, people quickly lose hope in his capabilities. An example of this is Hoover and the Great Depression. Hoover was president during the time of the Depression and even though he was the cause of the depression, people still blamed him for the loss of money and jobs. He implemented many policies like Public Works (appropriated $750 million for public works sti...

Difference Between Physical and Chemical Properties

Difference Between Physical and Chemical Properties Measurable characteristics of matter may be categorized as either chemical or physical properties. What is the difference between a chemical property and a physical property? The answer has to do with  chemical and physical changes  of matter. A Physical Property A  physical property  is an aspect of matter that can be observed or measured without changing its chemical composition.  Examples of physical properties  include color, molecular weight, and volume. A Chemical Property A  chemical property  may only be observed  by changing the chemical  identity of a substance. In other words, the only way to observe a chemical property is by performing a chemical reaction. This property measures the potential for undergoing a  chemical change.  Examples of chemical properties  include reactivity, flammability and oxidation states. Telling Physical and Chemical Properties Apart Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change. Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different. Look for Tell-Tale Signs of a Chemical Change Usually, you dont have the chemical reaction for a process. You can look for tell-tale signs of a chemical change. These include bubbling, color change, temperature change, and precipitation formation. If you see signs of a chemical reaction, the characteristic you are measuring is most likely a chemical property. If these signs are absent, the characteristic is probably a physical property.
