- Compare the uses of the words theory and hypothesis by scientists and by the general public.arrow_forwardDefine the terms experiment and theory. How are theory and experiment related? What is a hypothesis?arrow_forward1.23 Should the words theory and model be used interchangeably in the context of science? Defend your answer using information found in a web search.arrow_forward
- In Section 1.3 the statement is made that it is worthwhile for scientists, auto mechanics, doctors, politicians, and poets to take a scientific approach to their professions. Discuss how each of these people could use a scientific approach in his or her profession.arrow_forwardIn the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.arrow_forwardDefine the terms chemistry and matter.arrow_forward
- Which statements are true regarding observations, experiments, theories, hypotheses, laws, and scientific methods? Select all that apply. The correct sequence of events in the scientific method are: observation → hypothesis experiment → theory. A theory is a guess about something that has occurred in nature. O Scientific theories can not be tested and modified. O Hypothesis is tentative interpretation or explanation of observations.arrow_forwardThe Calcium content of a banana sample was homogenized and measured. Are the results comparable? Do they have the same precision? Please use data given.arrow_forwardIdentify each of the following statements as being most similar to a hypothesis, a law, or a theory. Explain your reasoning. (a) Falling barometric pressure precedes the onset of bad weather. (b) All life on earth has evolved from a common, primitive organism through the process of natural selection.arrow_forward

When a scientist looks at an experiment and then predicts the results of other related experiments, which type of reasoning is she using? Explain your answer.arrow_forwardClassify each description as a hypothesis, theory, or law.-An untested explanation based upon observation or known facts-A description that predicts what happens, but doesn't explain how-Scientists after many experiments, state that matter is composed of atoms- An explanation that has been tested and verified- A botanist guesses, but has not verified , that plants with one red-flowered and one white flowered parent will have pink flowersarrow_forwardThe Scientific Method Group of answer choices isn't used much in modern chemistry. is a strict set of rules and procedures that lead to inarguable fact is based on continued observation and experiment is just a theoryarrow_forward
