Which phase change involves an increase in the attractive force between molecule?
The phase change that involves an increase in the attractive force between molecules is condensation. During condensation, a gas transitions into a liquid as the molecules lose energy and move closer together, resulting in stronger attractive forces.
Kinds of attractive forces that need to be overcome to dissolve CsI in HF?
The primary attractive forces that need to be overcome to dissolve CsI in HF are ionic bonding between Cs+ and I- ions in CsI and hydrogen bonding between HF molecules. Ionic bonding involves the strong electrostatic attraction between oppositely charged ions, while hydrogen bonding involves the attraction between the partially positive hydrogen atom in HF and the partially negative fluorine atom in another HF molecule. Applying energy through stirring or heating helps disrupt these attractive forces and allow CsI to dissolve in HF.
Why does an increase in the number of molecules increase the pressure?
An increase in the number of molecules increases the frequency of molecular collisions with the container walls. With more collisions per unit time, the average force exerted by the molecules on the walls increases, resulting in an increase in pressure.
Why do water molecules cohere to form a liquid?
Water molecules cohere to form a liquid due to hydrogen bonding between the molecules. This hydrogen bonding leads to a net attractive force between the molecules, allowing them to stay close together in a liquid state.
What is the strongest attractive force between ch3och3 and ch3ch2ch3?
The strongest attractive force between CH3OCH3 (dimethyl ether) and CH3CH2CH3 (propane) is due to London dispersion forces. These forces are present in all molecules and increase with molecular size and mass. Therefore, in this case, propane would have stronger London dispersion forces due to its larger size and mass compared to dimethyl ether.
Which phase change involves an increase in the attractive force between molecule?
The phase change that involves an increase in the attractive force between molecules is condensation. During condensation, a gas transitions into a liquid as the molecules lose energy and move closer together, resulting in stronger attractive forces.
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.
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.
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 type of heat transfer involves molecules bumping into each other?
Conduction involves the transfer of heat through direct contact between molecules, where the molecules bump into each other and transfer kinetic energy.
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.
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.
How does this increase the rate of the reaction?
It increases the number of collisions between molecules. :)

Which property allows water to stick to glass?
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
