Question

This tetris ice cube game is available to play as long as the ice cubes remain ice. the game pieces weight 178 g , and the heat capacity of the room air, is 1.006 kj/kg- degree C , and the delta H fusion (water) = 333.55 kj/kg. how much energy will the game placed absorb as they are converted to water 0 degree C? If the game pieces are kept in a Styrofoam box that is 11 in size, and a temperature of 25 degree C, will the game pieces melt completely? Assume no heat transfer to or from the room air room that is outside the box, or to material in the box. What is the final temperature of the air in the box? if the box were filled with 0r gas, would the ice pieces melt faster or slower (heat capacity of Ar = 20.8 J/mol-K, or .52 J/g-K, and the density Ar = 1.784 g/ml degree C) A pressure cooker is a cooking device for might be the expected cooking time in the pressure cooker in that same 200 ml water? steam?

Explanation / Answer

1)a)energy absorbed = 0.178*333.55 (enthalpy*mass)

=59.3719 kJ

2)obviously no since the amount of heat provided by air is not sufficient.

3)Let the final temperature be T.so,

density fo air=1.225*10^-3 g/L

so mass of air in the box=1.225*10^-3 grams.

so the final temperature of air will be 0C.

d)since the density, specific heat capacity and density of argonis more than that of air, it will melt faster in presence of argon
