q is --_________ (positive OR negative) when heat is transferred from the surroundings to the system and w is --________ (positive OR negative) when work is done by the system on the surroundings. When a punctured car tire deflates (the tire is the system), the sign of w (work) for the system is -- _________ (positive OR negative) and the energy exchange is primarily due to --_________ (heat OR work.) When sweat evaporates from the skin, cooling the skin (the evaporating sweat is the system), the sign of q(heat) for the system is --_________ (positive OR negative) and the energy exchange is primarily due to --________ (heat OR work.)
