How does the surface area affect the rate of a reaction?
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
Is the inward force among the molecules of a liquid?
The inward force among the molecules of a liquid is Surface Tension
Why evaporation known as surface phenomena?
Evaporation is known as surface phenomena because molecules of water present on the surface of liquid are bonded weakly as compaered to inner molecules and when temperature increases hydrogen bonding between water molecules breaks.Due to this water molecules tend to evaporate.so that's why it is called as surface phenomena.
Does the type of container affect the evaporation?
Evaporation only happens at the surface. So a wider container that allows for a greater surface to be in contact with air, the faster the evaporation.
When water is in a container the surface of the water is curved this curve is call?
Meniscus is the curve at the surface of a liquid in a cylinder. It is caused by the adhesive and cohesive properties of water molecules. (Meniscus was incorrectly spelled in an earlier answer as "miniscus.")
Why does a meniscus make the liquid curve?
The meniscus looks curved because the liquid molecules cling to the sides of the container at the edges, but in the middle the surface "droops" because the molecules are not supported by the sides of the container.
Why is water meniscus convex when the container is fully filled?
The H20 molecules are bound together, it is called surface tension.
What is the curve at a liquid surface?
The meniscus, which is creaded by adhesion of the liquid particles to the surface of the container. Water meniscus domes upwards - the water has greater bonding to its own molecules; Mercury meniscus domes downwards.
How does surface area affect collision rate?
Surface area affects collision rate because the larger the surface area the more air resistance is acting on it, therefor a larger surface area can slow down collision rate.
What best describes how water evaporate?
The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere. But water is evaporated at any temperature.
How does the rate at which a container of water cools depends upon the surface area of the water exposed to the open air?
The rate at which a container of water cools depends on the surface area of the water exposed to the open air because the more water is exposed, the faster its molecules will cool.
What the atmosphere exert pressure on?
The atmosphere exerts pressure on various objects on the earth's surface. Air pressure is generally caused by the collision of the gas molecules with one another.
What word is used for the curved upper surface of a liquid in a tube?
It is called a MENISCUS caused by capillary action betweem the molecules of the liquid and the molecules of the container, and resulting from surface tension within the liquid. In addition: Adhesion: Making one material adhere to another.
Can water molecules evaporate at the surface or below the surface?
water molecules can evaporate at the surface but not below the surface
How are evaporation and condensation related to saturated air above a flat surface?
When you give energy to water in the form of Heat, all water molecules does not receive equal energy. Some water molecules have more energy than average energy of water molecules in a container, they will escape in to air in the form of Evaporation. When you closed the container with a plate, the evaporated molecules condensed in to water droplets after hitting no of walls in container (no chance for escape) and enter in to container again. After some time some molecules are evaporating and some molecules are condensing, at a certain stage the number of molecules that get evaporated becomes equal to the number of molecules that are condensing. This is the point of Saturation. Air also takes some finite amount of humidity in to it, it depends on ambient air temperature.
If you lay a steel needle horizontally on water it will float if you place the needle vertically into the water it will sink explain why?
Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks
Does water evaporate faster in a cup or pan?
Evaporation is the action of molecules escaping the bonds of neighboring molecules. At temperatures above absolute zero, molecules have energy that is expressed in motion. With enough of this motion, water molecules at the surface of water can break the bonds they have with their neighbors. They can escape the liquid and move into the air. When molecules leave the water, there is now less water, which is what we call evaporation. So if you have a dish that exposes more molecules to an area where they can escape the other molecules (in other words, the surface), obviously more will escape. A wide, flat, shallow container exposes many more water molecules to the surface than the same amount of water in a tall, narrow container.
