Question

question 7 of 10 a student redid the experiment of mixing room - temperature water and warm water. this time, she used half the original amount of warm water. how will the final temperature be different? a. it will be lower, because the amount of water in the mixture will be less. b. it will be the same, because all parts of the mixture will end up at the same temperature. c. it will be higher, because all parts of the mixture will end up at the same temperature d. it will be lower, because less thermal energy is transferred to the room - temperature water

Explanation:

When the amount of warm water is halved while the amount of room - temperature water remains the same, there is less thermal energy available from the warm water to raise the temperature of the mixture. So the final temperature of the mixture will be lower.

Answer:

A. It will be lower, because the amount of warm water is less.
