Ngā Whāinga Ako ^🔗

• To be able to describe what a change in temperature means
• To be able to describe the collision theory impacts of temperature
• To be able to carry out a change of temperature reaction

Particle Theory ^🔗

• This theory gives us the model of matter as a series of atoms with energy
• The greater the energy they posses, the more they vibrate and move around
• The lowest energy particles tend to be solids (not moving, but vibrating)
• The middle are liquids (freely moving past each other)
• The highest are gasses (filling the volume of a container)

Energy ^🔗

• To give matter energy, we heat it up
• This heat energy is seen as kinetic energy for individual particles (moving energy)
• As the temperature increases, they move faster

Impact on Collision Theory ^🔗

• If particles are moving faster, there are more collisions occuring
• If particles are moving faster, they have more kinetic energy and are more likely to surpass the activation energy
• This means that the probability that an individual collision is successful/effective also increases
• Therefore, temperature affects both the number of collisions and the probability that they are successful (reaction occurs).
