A37 g ice cube at -39°c is placed in a lake whose temperature is 35°c. calculate the change in entropy of the cube-lake system as the ice cube comes to thermal equilibrium with the lake. the specific heat of ice is 2220 j/kg·k. (hint: will the ice cube affect the temperature of the lake? )

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
