what's the difference between 改变 and 变 ？

They both mean to change, transform... so what makes them different usage wise?

For example:
来中国后， 他改变了对中国的看法。

天气变得越来越冷了。

谢谢

Basically, 改变 means initiative and 变 passiveness, or, the first one is a transitive verb, but the second one intransitive.
e.g.
you can see 如果你不能改变社会，你就只能改变你自己。nodoby say 变社会. Similar with this, there is a book name as 他改变了中国, in here, we cannot say 他变了中国.

for the 变, you can say 天气变暖了. you cannot say 天气改变暖了.

This explanation opened my eyes for a new way of looking at the difference between 1 character verbs and 2 character verbs...

But I think it goes deeper than that...

我问我的老师。。。

改变： 想法， 看法， 方式， 习惯
变： 得（形）， 越来越（形）

I do think it goes deeper than that, but until then, i'll take the above ground point for now.

Did you think the following 变 still is an adj?
1.变魔术
2.变天了
3.人生若只如初见，何事秋风悲画扇，等闲变却故人心，却道故人心易变

no...

but i'm not sure how to think about it in the passive/initiative form of view..

can you elaborate?

I think best answer was told by your teacher

改变 is a verb
变 is a adj

Good answer here though

the difference is subtle, we choose by feelings not by rules.dont try to find a rule,it doesnt exist,dont afraid make mistake,the more mistake u made,the better feelings u get

as a learner,the best way is find the wrong case first and avoid it.改变 is often used。变 is often with “得”or“了”

"dont try to find a rule,it doesnt exist"

This is the greatest bullshit I've ever read in this forum...

there is a rule, but yeah, sometimes with chinese its hard to explain, theres just sort of a 感觉... I think. 改变 is used when you say, can you change me? 能不能改变我? So it's better used as a verb. but... you could still use 变 as a verb too right? its not just an adjective like you can say: "我已经变了" hmm..
