The object’s potential energy is more when it is higher. As the object begins to move down, the potential energy will be turned into energy that can be used to overcome the object at the ground level. Why does kinetic energy decrease? There needs to be a force acting on the blocks to speed them up.

WebThe answer is the option (iii) Decrease. Explanation: Since kinetic energy increases with temperature, it can overcome intermolecular forces, and liquid starts flowing; hence the viscosity decreases.

WebJul 12, 2024 · The Arrhenius equation is k=Ae^ {-E_ {\Large a}/RT}. A minimum energy (activation energy,v E_a) is required for a collision between molecules to result in a chemical reaction. Plots of potential energy for a system versus the reaction coordinate show an energy barrier that must be overcome for the reaction to occur. WebMay 17, 2016 · 6. The kinetic theory says that temperature is the measure of the average kinetic energy. That would mean then: The temperature rises with the rise in kinetic energy. We know that when matter changes state 'latent heat' helps in 'breaking the bonds' at the transition phase and that this 'extra heat' is not noticed on a thermometer.
