Question

1. regan hypothesizes that an insulated cup would keep a drink cold longer than a paper cup. she records the temperature of a cold drink in both types of cups over a thirty - minute period. the drinks temperature in the insulated cup increases more slowly than in the paper cup. does her data support her hypothesis? why or why not?

Explanation:

Step1: Understand the hypothesis

Regan's hypothesis is that an insulated cup keeps a drink cold longer. A colder drink means a slower increase in temperature.

Step2: Analyze the data

The drink in the insulated cup has a slower temperature increase. A slower temperature increase implies the drink stays colder (closer to its initial cold temperature) for a longer time.

Answer:

Yes, her data supports her hypothesis. Since the drink in the insulated cup has a slower temperature increase, it means the insulated cup is keeping the drink cold longer as hypothesized.
