What happens to the motion of gas particles when temperature increases?
They start to move faster, therefore, the reaction will happen quicker. This is because there is more chance of a collision between the particles.
Do the particles themselves expand?
No, the particles themselves do not expand. Instead, it is the space between particles that increases during the expansion of the universe. This expansion affects the distance between galaxies and other large-scale structures, but the fundamental properties and sizes of individual particles, such as atoms or subatomic particles, remain unchanged.
What is An increase in the space between particles is called?
An increase in the space between particles is called expansion. This phenomenon typically occurs when a substance is heated, causing its particles to gain energy and move apart. Expansion can be observed in various states of matter, including solids, liquids, and gases. In gases, for example, the increase in space between particles leads to a decrease in density.
Why is it necessary for a collision between atomic particles to occur so a nuclear reaction may begin?
A collision between atomic particles is necessary to overcome the repulsion between their positively charged nuclei. When particles collide with enough energy, they can come close enough for the strong nuclear force to overcome the electrostatic repulsion, triggering a nuclear reaction. Without a collision, the forces involved are not strong enough to induce a reaction.
What two requirments must be met before a collision between two reactants particles is effective?
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.
What is the difference between an effective collision and ineffective collision of reactant particles?
An effective collision between reactant particles results in a chemical reaction, while an ineffective collision does not lead to a reaction because the particles do not have enough energy or correct orientation to break and form bonds. In an effective collision, reactant molecules collide with sufficient energy and in the correct orientation to overcome the activation energy barrier and form product molecules.
Is the energy of collision between two reactant particles is frequently absorbed by collision with a third particle?
Yes, the energy of collision between two reactant particles can be absorbed by collision with a third particle. This process, known as collision-induced relaxation, can lead to the redistribution of energy among the molecules involved in the collision.
Is expansion of matter due to expansion of particles rather than to increase particle spacing?
Expansion of matter is primarily due to an increase in the spacing between particles, rather than the expansion of individual particles themselves. When matter expands, the average distance between particles increases, leading to the overall expansion of the material. While individual particles may also exhibit some expansion due to thermal effects, the overall expansion of matter is more prominently driven by increased spacing between particles.
What happens to the motion of gas particles when temperature increases?
They start to move faster, therefore, the reaction will happen quicker. This is because there is more chance of a collision between the particles.
What is collision frequency?
Collision frequency refers to the rate of collisions between particles in a system or substance. It is influenced by factors such as the concentration of particles, temperature, and the nature of the particles themselves. A higher collision frequency typically indicates a more reactive system.
Why does heat cause expansion?
Heat causes expansion because it increases the speed at which particles vibrate within a substance, creating more space between them. This increased movement and spacing of particles lead to an overall expansion of the substance.
Why do particles of matter transfer thermal?
They transfer energy because as they gain heat which gives the particles more energy to move freely, the particles will inevitably collision into each other, so as this collision occurs the thermal energy is transfered to the newly hit particle, this would explain why heat is transfered quicker in solids, because the area between each particle is less than liquids and gases because it's particles are closely packed.
Why does the density is affected by the temperature?
thermal expansion between particles
Do the particles themselves expand?
No, the particles themselves do not expand. Instead, it is the space between particles that increases during the expansion of the universe. This expansion affects the distance between galaxies and other large-scale structures, but the fundamental properties and sizes of individual particles, such as atoms or subatomic particles, remain unchanged.
A collision in which kinetic energy may be transferred between the colliding particles but the total kinetic energy remains the same?
An elastic collision is a type of collision where kinetic energy can be transferred between colliding particles, but the total kinetic energy of the system remains constant before and after the collision. This means that energy is conserved in the collision process. Elastic collisions are characterized by no energy loss due to deformation or heat generation during the collision.
Diffbetween collision and scattering?
Collision refers to a direct physical interaction between particles that leads to a change in their paths or states, such as when two particles collide and merge or bounce off each other. Scattering, on the other hand, refers to a process where particles are deflected or redirected from their original path due to interactions, but without a direct collision occurring, such as when light is scattered by particles in the atmosphere.
When you heat particles do they expand?
Yes, when particles are heated, they gain kinetic energy and move more quickly, leading to an increase in volume or expansion of the material. This is because the particles move apart from each other, creating more space between them.
