Perfume sprayed from a bottle spreads more easily in a warm room of 25°C than in a cool room of 15°C. Which of the following correctly compares perfume molecules at 25°C to those at 15°C?
A. At 25°C, they have more mass.
B. At 25°C, they are moving faster.
C. At 25°C, they have less kinetic energy.
D. At 25°C, they are decreasing in volume.


Sagot :

At 25 degrees Celsius they have more kinetic energy and since it is a higher temperature it causes the molecules to vibrate and move faster. Therefore the correct answer is B.
