Final answer:
The hypothesis for an experiment comparing the effects of heat on carbon dioxide and air is that carbon dioxide will likely expand more than air due to its greater heat retention capability, influenced by the greenhouse effect.
Step-by-step explanation:
The question you're asking about is related to the properties of gases and how they react to heat, which is a fundamental concept in chemistry. Specifically, you're looking at how carbon dioxide compares with air when heated. In scientific experiments like this one, a hypothesis is a testable prediction about the outcome.
Given the historical context from Eunice Newton Foote's research, we know that carbon dioxide absorbs and retains heat differently than air. This is due to the greenhouse effect, where certain gases trap heat radiation. Considering this information, a plausible hypothesis might suggest that carbon dioxide will expand more than air when exposed to heat, because it is known for its higher heat retention capability.
Therefore, the most suitable hypothesis for your experiment might be:
A) The hypothesis is that carbon dioxide will expand more than air when exposed to heat.
