Explain the metal/laundry line which hang droop on a warm day in kinetic molecular model

Answer 1

In the kinetic molecular model, the metal/laundry line which hang droop on a warm day is explained by the fact that the molecules in the metal/laundry line are in constant motion. As the temperature increases, the molecules move faster and faster, causing the metal/laundry line to droop. This is because the molecules are pushing against each other, causing the metal/laundry line to become less rigid and more flexible. As the temperature increases, the molecules move faster and faster, causing the metal/laundry line to droop even more.

Answer 2

Water that vanish out of an open container

Answer 3

In the kinetic molecular model, water that vanishes out of an open container is explained by the fact that the water molecules in the container are in constant motion. Some of the molecules at the surface of the water have enough energy to break free from the surface tension and escape into the air as water vapor. This process is called evaporation.

When the air above the water is unsaturated with water vapor, more water molecules from the surface continue to escape and the level of the water in the container decreases. However, when the air above the water is saturated with water vapor, the rate of evaporation decreases and the level of the water in the container remains constant.

The amount of water that evaporates depends on the temperature, humidity, and air movement in the surrounding environment. Higher temperatures, lower humidity levels, and air movement all increase the rate of evaporation, causing the water to vanish more quickly.
