Physical Science SUSA (2020-21 A party shop delivers helium-filled balloons to homes and businesses. The owners realice from experience that on hot summer days they should inflate the balloons only three quarters full On cold winter days they can hilly
inflate the balloons. Which of the following is the BEST hypothesis to explain this observation?
Air outside the balloons leaks into the balloons
The helium gas is more active in the winter season
As the temperature increases, the helium in the balloons expands
Outdoor air pressure in the summer is less than indoor air pressure

As the temperature increases, the helium in the balloons expands.

Explanation:

I did it on the test

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
