When an exothermic reaction releases thermal energy, this energy is usually_____.
saw5 [17]

Explanation:

A chemical reaction in which heat or energy is released is known as an exothermic reaction.

On the other hand, when two objects are placed together and heat flows from hotter object to colder object then this process is known as conduction. Therefore, energy is dissipated in conduction process.

Since energy released released goes into the atmosphere and is not used anywhere.

Thus, we can conclude that when an exothermic reaction releases thermal energy, this energy is usually not useable to do work and it is dissipated by conduction.

Which of the following represents the greatest risk factor for a stroke
cupoosta [38]
The greatest risk factor, well that depends because their is quite a few risk factors. it depends where the person is having the stroke. so say someone was having a stroke in the library then you would have to move everything out of the way so they cant hurt themselves and call the ambulance straight away and tell them the signs the person is showing to tell you their having a stroke e.g. face dropping, slowed speech and cant hold their arm up in the air on their own.
