Astudent claims that water's polarity is the reason it has a high specific heat. what method could the student use to test his claim? perform research to see if other polar molecules have high specific heat. measure how much energy it takes to increase the temperature of water by one degree. mix water with an acid and test the new specific heat. determine how dissolving salt in water affects the specific heat.

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =

If state law mandates that elevators cannot accelerate more than 2.40 m/s2 or travel faster than 14.8 m/s , what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor? ?
