(a) Which is more likely to eventually be shown to be incorrect:an hypothesis or a theory? (b) A(n) _________ reliablypredicts the behavior of matter, while a(n) _________ providesan explanation for that behavior.
You observe that sugar dissolves more quickly in hot teathan in iced tea. You state that higher temperaturesincrease the rate at which sugar dissolves in water. Is thisstatement a hypothesis or a theory? Why?
Classify 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 flowers

- In 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_forwardWhich of the following are elements, and which are compounds? a NaOH; b BaCl2; c He; d Ag; e Fe2O3.arrow_forwardA student determined in a set of four experiments that the density of magnesium metal was 1.66 g/ml,1.65 g/ml, 1.67 g/ml, 1.67 g/ml.
