Question

question 6 of 10
a student redid the experiment of mixing room - temperature water and warm water. this time, she doubled the amount of warm water. how will the final temperature be different?
a. it will be higher, because the warm water will transfer more thermal energy to the room - temperature water.
b. it will be lower, because the room - temperature water will absorb more thermal energy from the warm water.
c. it will be the same, because all parts of the mixture will reach the same temperature.
d. it will be higher, because the amount of water in the mixture is greater.

Explanation:

When the amount of warm - water is doubled while the amount of room - temperature water remains the same, more thermal energy is available from the warm water to be transferred to the room - temperature water. According to the principle of heat transfer and conservation of energy in a mixture, this will result in a higher final temperature of the mixture.

Answer:

D. It will be higher, because the amount of water in the mixture with higher initial temperature is greater.
