Question

2.2.4 quiz: question 7 of 10 a class is performing an experiment to keep an ice cube solid as long as possible. which students actions could be a source of error in this experiment? a. maria checked her ice cube every half hour and forgot to reseal the container she put the ice cube in. b. carey repeated the experiment with three different ice cubes. c. jerrie measured the ice cube before it started to melt. d. jody used a different experimental design than carlos used

Explanation:

In an experiment to keep an ice - cube solid, opening the container (not resealing it) can introduce heat from the environment, causing the ice - cube to melt. This would be a source of error. Measuring the ice - cube or using different experimental designs with different ice - cubes are not errors in terms of keeping the ice - cube solid in the context of this experiment.

Answer:

A. Maria checked her ice cube every half hour and forgot to reseal the container she put the ice cube in.
