When it is raining it is advisable not to touch canvas tent from inside.Explain the behaviour of molecules
When it is raining, the canvas tent becomes wet due to the water molecules adhering to its surface. Inside the tent, the molecules of air and water vapor are in constant motion. When a person touches the wet canvas from inside, the molecules of air between the person's hand and the canvas get compressed. This results in an increase in the pressure exerted by the air molecules on the wet surface of the tent.
As a consequence of this pressure increase, some of the water molecules on the canvas get displaced towards the inside of the tent. This, in turn, can result in water seeping through the tent and making the interior wet and uncomfortable for the occupants.
Hence, it is advisable not to touch the canvas tent from inside when it is raining to prevent the compression of air molecules and the displacement of water molecules from the canvas surface to the interior of the tent.

Additionally, the act of touching the wet canvas from inside can also cause the fabric to stretch and weaken, resulting in the tent becoming more vulnerable to tearing or damage in the future. Therefore, it is recommended to avoid touching the wet canvas from inside and wait for the rain to stop before adjusting or handling the tent fabric as needed.
The behavior of molecules can help explain why it is advisable not to touch a canvas tent from the inside when it is raining. When it rains, water molecules in the form of liquid droplets are falling from the clouds and landing on the tent's surface.
Water molecules possess a property known as cohesion, which means they are attracted to each other and tend to stick together. This cohesion is a result of the attractive forces between the water molecules themselves. When the raindrops land on the canvas tent, the water molecules spread out and form a thin layer of liquid.
Now, inside the tent, there is likely to be warmer air compared to the outside environment. The warm air inside the tent increases the kinetic energy of the air molecules, causing them to move faster and collide with the liquid water molecules on the tent surface.
As a result of these collisions, the air molecules transfer some of their energy to the liquid water molecules. This energy transfer causes the liquid water molecules to have increased kinetic energy, which leads to an increase in the rate of evaporation.
Evaporation occurs when water molecules at the surface gain enough energy to break free from the liquid and enter the gas phase as water vapor. This process is continuous and happens at various speeds for different water molecules at the surface.
Now, if you were to touch the inside of a canvas tent during rainfall, your body heat would warm the air molecules near your skin. These warm air molecules would collide with the liquid water molecules on the tent surface, providing them with additional energy to evaporate.
As a result, touching the canvas tent from the inside can increase the rate of evaporation, which may compromise the waterproofing capability of the tent. It can lead to more water entering the tent, making it damp or wet inside.
Therefore, it is advisable not to touch the inside of a canvas tent during rainfall to minimize the transfer of heat energy from your body to the liquid water molecules on the tent surface, reducing the risk of increased evaporation and keeping the interior of the tent dry.
