Air is pumped into a bicycle tire at constant temperature.The pressure increases because:
A)more molecules strike the tire wall per second
B)the molecules are larger
C)the molecules are farther apart
D)each molecule is moving faster
E)each molecule has more kinetic energy

Question

Quizplus · Accepted Answer

When air is pumped into a bicycle tire at constant temperature, the number of molecules in the tire increases. This leads to more molecules striking the tire wall per second, thereby increasing the pressure. The size of the molecules, their distance apart, their speed, and their kinetic energy do not change in this scenario because the temperature is constant.
