Just about everyone at one time or another has been burned by hot water or steam. this problem compares the heat input to your skin from steam as opposed to hot water at the same temperature. 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. the heat capacity of liquid water 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.

explanation:

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
