Good day, the topic is about endothermic processes.
00:04
When a process absorbs heat from its surrounding, then that's called an endothermic process.
00:08
We want to establish or we want to give or cite two examples of endothermic process that are spontaneous.
00:15
By spontaneous, we mean that they happens naturally.
00:19
And that for letter, that's the first one, two examples of endothermic processes that are spontaneous.
00:27
And then for the next one, still endothermic process that is spontaneous at one temperature, but non -spontaneous at a different temperature.
00:41
So let's first address the first one.
00:44
So here we can think of melting of ice.
00:48
Well, naturally, it of course, under favorable conditions, such as room temperature...
