A student redid the experiment of mixing room-temperature water and warm water. This time, she doubled the amount of room-temperature water. How will the final temperature be different?

• It will be higher, because all parts of the mixture will end up at the same temperature.

• It will be the same, because all parts of the mixture will end up at the same temperature.

• It will be higher, because the amount of water in the mixture is greater.

• It will be lower, because the temperature of the room-temperature water will not increase as much.

A class is performing an experiment to keep an ice cube solid as long as possible.

Which student's actions could be a source of error in this experiment?

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

• Carey repeated the experiment with three different ice cubes.

• Jody used a different experimental design than Carlos used.

• Jerrie measured the ice cube before it started to melt.
