This is an example of scientific investigation being led by inductive reasoning.
Explanation:
Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.
The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.
Volume of Hydrogen V1 = 351mL Temperature T1 = 20 = 20 + 273 = 293 K Temperature T2 = 38 = 38 + 273 = 311 K We have V1 x T2 = V2 x T1 So V2 = (V1 x T2) / T1 = (351 x 311) / 293 = 372.56 Volume at 38 C = 373 ml
CO2 consists of individual molecules with one central carbon atom double bonded to two oxygen atoms. Silicon does not form double bonds with oxygen. CO2 is gas but SiO2 is a solid because SiO2 has a giant molecular structure. CO2 has a simple molecular structure, and because of this, CO2 is gas but SiO2 is solid at room temperature.
