Answer

B. A random sample

Explanation

In a experiment, a scientific evidence is the information obtained from scientific research which is objective and unbiased. Validity of the results occurs when it is possible to apply a conclusion drawn in the context of a scientific experiment to the general understanding. Control scenarios are necessary when testing the effects and impacts of results.

you can't see the options

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
