Helium is a naturally occurring, lighter--air gas that is used commercially to fill baloons. which statement best describes how science was impacted by society in regards to helium? a. helium has been mass produced to meet consumer demands for parties b. helium has been proven to be lighter than air c. scientists observed that helium will cause balloons to float d. scientists have found that helium is naturally occurring

C

Explanation:

As we know that in the air ,nitrogen is the most abundant gas after nitrogen second abundant gas  is oxygen.Helium gas is also present in the air but not so large in portion,only little part.

Helium is naturally occurring ,lighter than air gas is used commercially to fill balloons because Scientists observed that helium gas is lighter and will cause balloons to float.

So our option C is right.

the right answer is 0.3 meters per second
