When you put water into the bottle, you have to let that same volume of air escape. If the funnel were a tight fit, that air would have to come up the tube of the funnel, disrupting the flow of the liquid. The result would be erratic water flow, sort of a "gurglegurgle gurgle" flow instead of a continuous flow.
The ridges near the base of the funnel allow air to escape from a container it is inserted into. Without the ridges, air in the container would be compressed and would tend to prevent filling as the level of liquid rises.
The ridges on a funnel prevent it from fitting tightly in a bottle to allow air to flow in while pouring liquid. This prevents a vacuum from forming in the bottle, facilitating a smoother pour.
If a bottle is tightly sealed and heated, the pressure inside the bottle will increase as the air or gas inside expands. This pressure build-up could potentially lead to the bottle exploding if the pressure becomes too great for the bottle to contain. It is important to be cautious when heating sealed containers to prevent accidents.
Using a dry and clean spatula helps prevent contamination of the reagent. Spooning out small amounts of solid ensures accurate measurement and avoids waste of reagent. Remember to close the reagent bottle tightly after use to maintain its integrity.
A weighing bottle is used to accurately weigh small quantities of solid substances. It helps prevent contamination or loss of material during the weighing process.
Chemicals are kept tightly closed to prevent contamination, spills, and evaporation, which can compromise their stability and safety. Opening the bottle exposes the chemical to potential contaminants in the air, so it should only be done when necessary to remove a specific quantity.
Bottles of chemicals are kept tightly closed to prevent the escape of harmful vapors into the environment and to minimize the risk of spills or accidents. Opening the bottle only when needed helps to control exposure to potentially hazardous chemicals and maintain the quality and stability of the chemicals inside.

Turning a screw, opening a jar or bottle, operating a faucet, and adjusting a plumbing fitting all function on the same principle. Turning to the left loosens the plumbing fitting; turning to the right tightens it. Remembering this simple rhyme can prevent a bad seal and stripped fittings.

Heat causes materials to expand. Hopefully, the bottle top will expand more rapidly than the bottle and therefore the top will not adhere so tightly to the bottle and it can more easily be unscrewed.
