A50.0-gram block of copper at 10.0°c is carefully lowered into 100.0 grams of water at 90.0°c in an insulated container. which statement describes the transfer of heat in this system? (1) the water loses heat to the block until both are at 10.0°c. (2) the block gains heat from the water until both are at 90.0°c. (3) the water loses heat and the block gains heat until both are at the same temperature that is between 10.0°c and 90.0°c. (4) the water gains heat and the block loses heat until both are at the same temperature that is between 10.0°c and 90.0°c.
