What happens to the vapor pressure as liquid evaporates into a partially filled container?

Options

  1. AThe vapor pressure decreases.
  2. BThe vapor pressure increases.
  3. CThe vapor pressure remains constant.
  4. DThe vapor pressure becomes zero.

Correct answer

B. The vapor pressure increases.

Step-by-step solution

Initially, as the liquid evaporates, the pressure exerted by vapors on the container's walls (vapor pressure) increases.
