Ques: Answer the following question given this paragraph: Convection is the transfer of heat by a current. Convection happens in a liquid or a gas. Air near the ground is warmed by heat radiating from Earth's surface. The warm air is less dense, so it rises. As it rises, it cools. The cool air is dense, so it sinks to the surface. This creates a convection current, like the one in Figure below . Convection is the most important way that heat travels in the atmosphere. Q: What is the transfer of heat by a current? Choices: - radiation - combustion - diffusion - convection A:
Ans: convection
(Q).
Answer the following question given this paragraph: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their chemical properties. A modern version is shown in Figure 2.7 "A Modern Periodic Table". Most periodic tables provide additional data (such as atomic mass) in a box that contains each element's symbol. The elements are listed in order of atomic number. Q: The periodic table is one of the cornerstones of chemistry because it organizes all the known elements on the basis of their what? Choices: - size properties - liquid properties - acid properties - chemical properties A:
(A).
chemical properties
Ques:Answer the following question given this paragraph: The scientist must next form a conclusion. The scientist must study all of the data. What statement best explains the data? Did the experiment prove the hypothesis? Sometimes an experiment shows that a hypothesis is correct. Other times the data disproves the hypothesis. Sometimes it's not possible to tell. If there is no conclusion, the scientist may test the hypothesis again. This time he will use some different experiments. No matter what the experiment shows the scientist has learned something. Even a disproved hypothesis can lead to new questions. Q: If no conclusion is reached after an experiment, the scientist may retest what? Choices: - conclusion - materials - suggestions - hypothesis A:

Ans:hypothesis
