Two cups of coffee, one that is at 10°c and one that is at 20°c, are mixed. which statement about the temperature of the mixture is correct? '

a. there is no kinetic energy transfer so the temperature of the coffee in the warmer cup is the final temperature.
b. the kinetic theory dictates that the temperature of the coffee in the cooler cup is the final temperature.
c. energy is transferred from faster moving molecules to slower moving molecules, and the result is the average of 15°c.
d. energy transfer occurs as the molecules collide, and the result is additive; the final temperature is 30°c.

Option (D) is the correct answer.

Explanation:

When both the cups of coffee with different temperature are added together then molecules of coffee with higher temperature will collide rapidly with molecules of coffee with lower temperature.

As a result, molecules at lower temperature will also gain some more kinetic energy.

Thus, we can conclude that statement about the temperature of the mixture energy transfer occurs as the molecules collide, and the result is additive; the final temperature is 30°C, is correct.

why is cellular respiration important for homeostasis?
