When particles collide, they transfer energy and momentum.
All particles of all things are in constant motion. Particles in a liquid collide, but the rate is subdued by the viscosity of the liquid.
Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires. Overall, photoelectric detectors are considered more effective in detecting smoke particles.
Two molecules must collide with each other.
For a collision between two reactant particles to be effective, two key requirements must be met: first, the particles must collide with sufficient energy to overcome the activation energy barrier, allowing the reaction to proceed. Second, the particles must collide with the proper orientation, ensuring that the reactive parts of the molecules are aligned correctly to facilitate the formation of products.
rate of collisions, the right orientation, enough energy
You seem to have answered your own question-it is the collisions that transfer energy
The particle nature of light is illustrated by the photoelectric effect.
Photoelectric Effect, Compton Effect, and Pair Production.
When two photons collide with each other, they can either scatter off in different directions or combine to create new particles, such as an electron and a positron. This process is known as pair production.
Since they collide at very high energies, it is expected that they will produce some new particles, that were not yet observed previously.
