Endothermic Reactions vs. Exothermic Reactions Worksheet Process System Exo Endo Explanation 1. An ice cube melts after being left out on the table. 2. Cooking an egg in a frying pan. 3. Burning a match. 4. Dynamite explodes, causing the destruction of a building. 5. Making ice cubes. 6. A puddle of water evaporates. 7. Plants make sugar through photosynthesis.

Transcript

00:01 When we talk about exothermic and endothermic process, so exothermic process, in the exothermic process, we say that heat is released by the system.

00:13 Heat is released by the system.

00:20 Whereas, in the case of endothermic process, endothermic process, heat is absorbed by the system.

00:43 Now we can say that in the first part we have is melting of ice.

00:48 So here in this case what is going to happen is if we consider the melting of ice part.

00:52 So first of all we have is melting of ice.

01:00 In this case here what we can say is this is going to be an endothermic process.

01:09 Endothermic process reason being very simple that in this process heat is being absorbed endothermic process reason heat absorbs and melting starts second is the frying of eggs in a pan so here we can say that or we can write cooking an egg in a pan.

01:47 So yeah, what is going to happen? it is again going to be endothermic reaction.

01:51 Endothermic, because reason being very simple that heat absorbed for cooking.

02:07 Next, we have this third process, burning of match.

02:14 Burning of match.

02:17 So in this case, what is going to happen is burning of match is burning of match is going to be an exothermic reaction exothermic reaction reason is heat is evolved heat is evolved next we have is dynamite explode dynamite explode this is again going to be exothermic reason that tremendous amount of tremendous amount of heat evolved.

03:11 Next process we have is making ice cubes...
