Which of the following best describes what happens when ice is placed in a warm glass of water?
a. the ice floats to the top, but small pieces break off and are suspended in the liquid to cool it through convection
b. heat from the glass moves through the liquid to melt the ice through radiation
c. the heat from the surrounding liquid is transferred to the ice through conduction
d. the ice transfers the cold temperature to the surrounding water through convection
