Complete each of the statements below.

When work is done on a system by its surroundings, the sign of w is                           [ Select ]                       ["positive", "negative"]         .

When work is done by a system on its surroundings, the sign of w is                           [ Select ]                       ["negative", "positive"]         .

When q has a negative sign, we can say that heat is transferred                           [ Select ]                       ["from", "into"]         the system                            [ Select ]                       ["from", "into"]         its surroundings.

If ∆U for a system is 0 and w is negative, then q must be                           [ Select ]                       ["positive", "negative"]         .
