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.
Does particles in gases expand when heated?
This is because when heat is applied to particles, they gain energy, therefore they travel faster and space out. The volume will increase though the density will decrease. So matter will always expand when exposed to heat.
How do catalysts affect collision theory?
A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
Why is it necessary for a collision between atomic particles to occur so a nuclear reaction may begin?
High Energy produced with high velocity which required for nuclear reaction
Why can't liquids be heaped like solids?
because the force of attraction between the molecules of solid is quite high. because in solids the particles are compressed together. there isn't much space between these particles. however in liquids the space between particles is more and hence it can move more freely.:)
What is the difference between an effective collision and ineffective collision of reactant particles?

Why does the density is affected by the temperature?
thermal expansion between particles
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.
A collision in which kinetic energy may be transferred between the colliding particles but the total kinetic energy remains the same?
This is called an elastic collision. In this case both momentum and kinetic energy is conserved.
Does particles in gases expand when heated?
This is because when heat is applied to particles, they gain energy, therefore they travel faster and space out. The volume will increase though the density will decrease. So matter will always expand when exposed to heat.
What do you mean by propagation of sound?
Propagation of sound in a medium (like the atmosphere) is the collision between the medium particles driven by a vibrating object
How is thermal expansion being affected by temperature?
Thermal Expansion is being affected by temperature because the substance's temperature increases and therefore it makes the particles move faster and spread out. Also, it causes more space between the particles which then makes the substance expand. Alcohol in a thermometer is expanding and that is also caused by Thermal Expansion. Not only that but, Mercuy is also used in thermometers which again like I said before is caused by Thermal Expansion which to then makes the thermometer expand the red liquid.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
How do catalysts affect collision theory?
A catalyst is a substance that increases the rate of a reaction without being used up. Some catalysts work by giving the the reacting particles a surface to stick to where they can make contact which increases the amount of collisions between the particles. Therefore a catalyst effects collision theory by speeding up a reaction.
Why do particles of matter transfer thermal energy?
Matter is needed to transfer thermal energy by conduction and convection. Conduction happens through a substance when there is a difference in thermal energies between regions. Convection is the movement within a fluid caused by hotter material to rise and colder material to sink and transfer heat.
