Calculate the change in entropy when 1.00 kg of water at 100 degree c is vaporized and converted to steam at 100 degree c. assume that the heat of vaporization of water is 2256 times 103 j/kg. calculate the change in entropy when 1.00 kg of ice is melted at 0 degree c. assume that the heat of fusion of water is lf = 3.34 times 105j/kg. is the change entropy greater for melting or for vaporization? the change entropy greater for melting the change entropy greater for vaporization

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
