The figure below, called a heating curve, represents the temperature of a block of ice as thermal energy is added. (The ice melts into water and then vaporizes into steam.) The thermal energy required to change phase from solid to liquid is calculated using the equation Q = mL4, where is called the (latent) heat of fusion. The thermal energy required to change phase from liquid to gas is calculated using the equation Q = mL,, where L, is called the (latent) heat of vaporization. Cice = 2100 J/kg-K; water = 4186 3/kg-K; Csteam = 2000 3/kg-K; 44 of water = 3.33 x 105 3/kg; L, of water = 2.26 x 105 3/kg Thermal Energy Qualy A snowball made of ice at -11.2 degrees Celsius is thrown at a brick wall. Assuming no energy is lost to the wall or surrounding air, how fast would the snowball have to be thrown in order to completely vaporize upon impact? Include units in your answer. More information.

Question

The figure below, called a heating curve, represents the temperature of a block of ice as thermal energy is added. (The ice melts into water and then vaporizes into steam.) The thermal energy required to change phase from solid to liquid is calculated using the equation Q = mLf, where Lf is called the (latent) heat of fusion. The thermal energy required to change phase from liquid to gas is calculated using the equation Q = mLv, where Lv is called the (latent) heat of vaporization.

 


cice = 2100 J/kg·K; cwater = 4186 J/kg·K; csteam = 2000 J/kg·K; Lf of water = 3.33 x 105 J/kg; Lv of water = 2.26 x 106 J/kg
