Yes, the temperature inside a protostar can increase due to particle collisions. As the protostar forms, gravitational forces cause gas and dust to collapse, leading to increased density and pressure. This compression raises the temperature, and as particles collide with greater frequency and energy, the thermal energy of the system increases. Once the core temperature becomes sufficiently high, nuclear fusion can begin, marking the transition to a main-sequence star.
What else can I help you with?
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What is the connection between temperature collisions and reaction rate?
More collisions between particles of matter means a faster reaction rate. When you increase the kinetic energy of a sample of matter, you increase the number of particle collisions, as well as the force with which they collide. This in turn increase the rate of reaction.
Is it an increase when particles collide more often?
Yes, an increase in the frequency of particle collisions typically indicates a rise in the reaction rate for chemical or physical processes. This can occur due to factors such as increased temperature, higher concentration of reactants, or greater pressure, all of which enhance the likelihood of collisions. More frequent collisions can lead to more successful interactions, facilitating reactions and energy transfer.
What must be done to increase the rate of reaction?

How does temperature or heat energy affect particle movement?
Temperature is a measure of particle movement. An increase of temperature, in a sense is an increase of the average movement of the particles within the substance, to include vibrations, spins, and lateral movement.
When the temperature of a particle of matter rises there is an increase in the?
kinetic energy:)
When the temperature of a particle of matter rises there is an increase in what?
kinetic energy:)
What factors increases the reaction rate by increasing particle speed?
Increasing the temperature of the system leads to higher particle speeds, increasing the chances of collisions between reactant molecules. This in turn increases the reaction rate as a higher proportion of collisions will have sufficient energy to overcome the activation energy barrier.
The speed of the particles in a substance change when what changes?
electrons
What particle property changes with change in temperature?
Temperature affects the average kinetic energy of particles. As temperature increases, particles have higher kinetic energy, which can impact their speed, collisions, and interactions with other particles.
How does temperature affect mean free path?
Mean free path, the average distance a particle travels between collisions, is inversely related to temperature. As temperature increases, the kinetic energy of particles rises, leading to more frequent collisions and thus a shorter mean free path. Conversely, at lower temperatures, particles move more slowly, resulting in fewer collisions and a longer mean free path. Therefore, higher temperatures generally decrease mean free path, while lower temperatures increase it.
What factors change the rate of chemical reaction?
Adding a catalyst to the process will make the chemical reaction go faster. Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.
