Collisions of atoms and molecules in air with objects?
its gas pressure
Are collisions between solvent molecules and solute are more frequent at lower or higher temperatures?
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
What a temperature increases affect collisions between molecules?
thermal effect
What is the molecules of an ideal gas?
Perfectly elastic collisions, point masses (no volume of individual molecules), no intermolecular attractions.
How do you increase the number of collisions between molecules?
heating, stirring, surface area
Why is Americium-241 used in smoke detectors?
Americium-241 is a radioactive isotope and used in smoke detectors to ionize the air (gives air molecules a charge). This allows a small current t flow between two contacts placed in the air chamber. When smoke particles enter the chamber, they attach themselves to the ionized molecules (by electrostatic attraction) effectively making them bigger and slowing the current. The detector then goes off when the current slows.
Are collisions more common between gas molecules or liquid molecules?
Liquids. There are more collisions, but the majority are at lower energies.
Collisions of atoms and molecules in air with objects?

Are collisions between solvent molecules and solute are more frequent at lower or higher temperatures?
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
How does this increase the rate of the reaction?
It increases the number of collisions between molecules. :)
What a temperature increases affect collisions between molecules?
thermal effect

Perfectly elastic collisions, point masses (no volume of individual molecules), no intermolecular attractions.
What happenes to the particels of a gas when there are fewer of them?
This is the ideal gas with no collisions between molecules..
Will higher temperatures cause more collisions?
Between gas molecules, yes, it will.
How do you increase the number of collisions between molecules?
heating, stirring, surface area
What do collisions of gas molecules with the container walls produce?
The pressure
Does the collision of molecules create heat?
The number of collisions with enough energy to react increases.
