Assume that water and steam, initially at 100°c, are cooled down to skin temperature, 34°c, when they come in contact with your skin. assume that the steam condenses extremely fast. assume the heat capacity of liquid water and steam is c=4190j/(kg*k).
how much heat h1 is transferred to the skin by 25.0 g of steam onto the skin? the latent heat of vaporization for steam is l=2.256

(b) its velocity and its acceleration are both zero. (c) its velocity is perpendicular to its acceleration. (d) its acceleration depends on the angle at which the ball was thrown.
