Question

heat is extracted from a certain quantity of steam at 100degrees C As a result, the steam changes in ice at 0degrees. If this energy were used to accelerate the ice fromrest, what would be the linear speed of ice? (just forcomparison, bullet speeds fo 700 m/s are common) I don't even understand this one heat is extracted from a certain quantity of steam at 100degrees C As a result, the steam changes in ice at 0degrees.

Explanation / Answer

temp of steam t = 100 oC temp of ice t ' = 0 oC energy extracted is Q = m L + m C dt + m L ' where L = latent heat of vaporisation = 2260.44 * 10 ^ 3J / kg            C= specific heat = 4186 J / kg o C           dt =100 oC            L' = latent heat of fusion = 334.88 * 10 ^ 3 J / kg So, Q = m * 3.01392 * 10 ^ 6 J Kinetic energy of ice K = ( 1/ 2) m v ^ 2 from problem , K = Q ( 1/ 2) m v ^ 2 = m * 3.01392 * 10 ^ 6 from thia linear speed v = 2455.16 m / s
