Answer:
An increase in temperature indicates that the molecules of gas speed up.
Explanation:
The molecular kinetic theory states that the average kinetic energy of gas particles (molecules) is proportional to the absolute (Kelvin) temperature of the gas, and all gases at the same temperature have the same average kinetic energy.
Therefore, as the temperature increases so the kinetic energy increases.
It is also known that the kinetic energy is proportional to the squared speed of the particles, therefore the higher the kinetic energy the average speed of the molecules:
- higher temperature → higher kinetic energy → higher average speed
The correct answer Organism
Not sure if this is right but this is what I think
Thermal energy added: Particles move faster, Kinetic energy increases, Temperature increases
Thermal Energy removed: Particles move slower, Kinetic energy decreases, Temperature decreases
