Degree or percentage or proof (alcohol) / focus (on)

1. How concentrated does alcohol have to be before it will no longer freeze? or What proof does alcohol have to be before it won't freeze?

As a comment on the science, that question doesn't make a whole lot of sense. Even pure ethanol will freeze if you get it cold enough. You'd have to specify a temperature before anyone could answer your question.

2. How do you change the dept

Thank you so much CSnyder,

I had a question

What proof does alcohol have to be before it won't freeze? (does this not sound weird "before with won't"?

Can you say

What abv does alcohol have to be before it no longer freezes?

For 2

If one didn't know a whole lot about cameras, would my sentence be grammatical and correct?

Thank

If I didn't think it sounded natural I wouldn't have suggested it

"What abv does alcohol have to be before it no longer fr

Hello,

I'm sorry to bother you but could you tell me if this is correct?

How would you say both parts naturally please?

This alcohol is the same proof as that one.

This alcohol is the same abv as that one. They are both 12 degrees/12 proof/12 abv.

Hello CSnyder,

I had one question:

How would a native express this:

What proof alcohol is that? (pointing to a bottle of vodka for example)

What would you say in that situation?

Thank you

That seems fine to me, although you can drop the word "alcohol" if you want.

Is that the how would would say it in that situation, If I was at a supermarket and asked someone that, how would I?

Thank you CSnyder
