It seems to me that every answer there is correct.  All 5 answers could improve and change the results of a scientific experiment.  I suppose I would say check off all 5 answers.

Answer:

The correct answer will be options-

1. new hypothesis

2. technological inventions

3. repetition of the experiment

Explanation:

A scientific theory is a well-substantiated statement which explains any natural phenomenon in depth.

A theory is the elaborate explanation of the predicted hypothesis which becomes a theory when it has proved by the researcher and the fellow scientists.  

The life of a theory is durable which can be changed or modified when a new hypothesis is generated on the same issue or scientific question which explains the phenomenon more accurately.

The advancement in the technology can add knowledge to the existed theory which could lead to the modification of the theory. Also, if the repetition of the results of the old experiment does not support the theory can lead to the change in the theory.

Thus, the selected options are the correct answer.

Darya [45]
<span>The average speed of the gas is related to the kinetic energy of the gas.  The kinetic energy of the gas is also related to the temperature of the gas. If the average speed of the gas is closer to zero, it means that it has very low motion or kinetic energy. This can be inferred that the gas has a very low temperature. At absolute zero, the motion of all the gas molecules stops. This means that the kinetic energy of the gas is also zero. Zero kinetic energy means zero average speed.</span> <span>So, the answer is cylinder B. The average speed of the gas in cylinder B is closest to zero.</span>

16. Explain why antifreeze is used in vehicle radiators. Use your knowledge of the properties of
Fynjy0 [20]

Answer:

Antifreeze is whats used to keep your engine cool without freezing.

Explanation:

it keeps the engine from overheating.

It also prevents corrosion.

Here is a quote from google "Antifreeze works because the freezing and boiling points of liquids are “colligative” properties. This means they depend on the concentrations of “solutes,” or dissolved substances, in the solution. A pure solution freezes because the lower temperatures cause the molecules to slow down"

That quote is from "The Science Behind Antifreeze"

How is the Crystal lattice of an ionic compound different from the Crystal formation of a metallic compound
den301095 [7]

Answer:

Explanation: For most longer adjectives, the comparative is made by adding the word "more" (for example, more comfortable) and the superlative is made by adding the word "most" (for example, most comfortable). If a 1-syllable adjective ends in "e", the endings are "-r" and "-st", for example: wise, wiser, wisest.

What type of reaction is shown below?
natima [27]
An exothermic reaction is a type of chemical reaction in which energy is released to the environment in form of heat or light. Endothermic reaction in the other hand is a chemical reaction where energy is taken from the surroundings and thus the surroundings end up with less energy than they started with. In this case; the above reaction is an Exothermic reaction (heat is being released to the surroundings).
