For an experiment, you place 15 g of ice with a temperature of -10 C into a cup and label A. You also place 25 g of ice at the same temperature into another cup and label it B. Which of the following statements is true?
A) The average kinetic energy of the ice in cup A is less than that in cup B.
B)The average kinetic energy of the ice in cup A is greater than that cup in B.
C)The average kinetic energy of the ice cup A is equal to that in cup B.
D)The average kinetic energies of the ice in cup A and the ice in cup B are not comparable.
I really need this answered.
it is C
does any one know
To determine which statement is true, you need to understand the concept of temperature and its relation to the average kinetic energy of particles.
The kinetic energy of particles is directly related to their temperature. The higher the temperature, the greater the average kinetic energy of the particles.
In this case, both cups contain ice at the same temperature of -10°C. Since the ice in both cups is at the same temperature, we can conclude that the average kinetic energy of the ice particles in cup A should be equal to the average kinetic energy of the ice particles in cup B.
Therefore, the correct statement is:
C) The average kinetic energy of the ice in cup A is equal to that in cup B.
