What happens to an object as its thermal energy increases?
NemiM [27]

Answer:

It heats up.

Explanation:

Because thermal energy is based off the temperature of an object and the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increase.

According to collision theory, the rate of reaction depends on atoms colliding in the correct _________ with enough ________ for
kenny6666 [7]

Answer: orientation , energy , frequency

Explanation:

According to the collision theory , the number of collisions that take place per unit volume of the reaction mixture is called collision frequency. The effective collisions are ones which result into the formation of products.

Effective collisions depends on the following  two factors:-

1. Orientation factor: The colliding molecules must have proper orientation at the time of collision to result into formation of products.

2. Energy factor:  For collision to be effective,  the colliding molecules must have energy more than a particular value called as threshold energy.
