Awell-insulated copper rod (thermal conductivity of 388 w/m k) is 50 cm long and has a cross-sectional area of 10 cm/- one end of the copper rod is in contact with a block of ice at 0 c, the others end is in boiling water are 100 c. heat of vaporization for the saturated steam at 100 c is 2257 kj/kh. the heat of fusion for ice at 0 c is 334kj/kg. how much ice melts in 1 min? if the block had a mss of 4 kg, how long would is take to raise the temperature of 6 c? the specific heat of water is 4.18 kj/kg c.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
