Passing a selector as an argument

I have this function but instead of writing $('.front img') , $('.bottom img') and so on I would like to pass that value as the argument of the next function

function revertHover(){
        $('.front img').css({"opacity" : 0.7,
                             "-webkit-transform" : "scale(1)",
                             "-moz-transform" : "scale(1)"});
        $('.PT').detach();
}

I have tried this but is not working :

function revertHover(face){
        $(face).css({"opacity" : 0.7,
                             "-webkit-transform" : "scale(1)",
                             "-moz-transform" : "scale(1)"});
        $('.PT').detach();
}

$('.front').hover(
    function(){
        $('.front img').css({"opacity" : 1,
                             "-webkit-transform" : "scale(2)",
                             "-moz-transform" : "scale(2)"});
        $('.popup').append("<p class='PT'>some stuff</p>).hide().fadeIn(800);
    }   
    ,revertHover(" '.front img' ") );

I am sure there is something pretty wrong, thanks a lot in advance for your help, I really appreciate!

You don't need the double quotes in

revertHover(" '.front img' ")

the following should work,

revertHover(".front img")

or

var side = $(".front img");
revertHover(side);

Thanks for your answer, it helped me to solve the problem because that indeed was one mistake I had, the other one is that I found out I have to call the revertHover function within another function as the second handler in the hover method like this: 

var frontSide = $(".front img");

function revertHover(side){
        side.css({"opacity" : 0.7,
                             "-webkit-transform" : "scale(1)",
                             "-moz-transform" : "scale(1)"});
        $('.PT').detach();
}

$('.front').hover(
    function(){
        $('.front img').css({"opacity" : 1,
                             "-webkit-transform" : "scale(2)",
                             "-moz-transform" : "scale(2)"});
        $('.popup').append("<p class='PT'>some stuff</p>).hide().fadeIn(800);
    }
//This is the other function I was talking about    
    ,function(){
        revertHover(frontSide);
    }
);

Thanks again Kyle!

i would suggest pasting your code into jsfiddle so we can see how it works together w/ the html etc. and then link your jsfiddle here.

sorry - meant to comment not post as an answer.
