The attractive forces binding the molecules of a solid can be weakened by?
The attractive forces between molecules can be weakened by supplying them with heat energy.
How do you increase the number of collisions between molecules?
heating, stirring, surface area
What is the weak attractive forces which exist between water molecules?
almost positive they are Vander waals forces
Van Der Waals Forces Are Attractive Forces Between Molecules?
Van der waals forces (ie induced dipole-dipole interactions) is a weak intermolecular attraction that exist but one molecule and another whether polar or non-polar.
Whats the difference between adhesion and cohesion?
Adhesion is the attraction between two molecules of different substances.cohesion is the attraction between molecules of the same substances.
The attractive forces binding the molecules of a solid can be weakened by?
The attractive forces between molecules can be weakened by supplying them with heat energy.
What are the attractive forces between gas molecules?
gravity, no jk
What is the attractive forces between like molecules?
Cohesive force is the attractive force between like molecules. Cohesive forces are also known as intermolecular forces and can also be repulsion forces.
What is the attractive force between water molecules known as?
This is an intermolecular attraction of water molecules, associated by hydrogen bonds.
Why does an increase in the number of molecules increase the pressure?
The great the density the higher the air pessure.
The attractive force between masses is known as?
cohesion: the intermolecular attraction between like molecules
What is the difference between agglutination and precipitation?
Agglutination involves the clumping together of insoluble molecules. So you easily this happening with the naked eye. Precipitation involves the aggregation of soluble molecules.
What are the characteristic of matter?
Characteristics of matter -Particles of matterare infinitely small;have space between them;are continuously moving;have attractive forces between particles;have an increase in kinetic energy with an increase in temperature.On point 4 - gas particles are considered to have no attractive forces between one another and act totally independently of one another. However, there must be some attractive forces between particles as the pressure increases and/or the temperature decreases of gas would never condense to a liquid.
How does this increase the rate of the reaction?
It increases the number of collisions between molecules. :)
Why is E-stilbene solid and Z-stilbene liquid?
The attractive forces between the molecules in E-stilbene must be stronger than the attractive forces holding Z-stilbene together. The degree of attraction between molecules in a substance always accounts for its state of matter at a given temperature.
Why Physisorption is multilayered and chemisorption is monolayered?
physisorption involves van der wall attractive forces between adsorbent and adsorbed , This may result on the accumulation of many layers of the molecules on the surface. Chemosorption involves formation of chemical bonds between adsorbent and adsorbed molecule. Adsorbent have some functional groups or atoms on its surface with unsatisfied valences, once these valences are satisfied they don't undergo bond formation with more adsorbed molecules and only single layer is formed.
Which kind of heat transfer involves direct contact between the molecules of the hotter object and the colder object?
Conduction involves the direct contact between two objects to transfer heat.
