A bowl of hot soup and a glass of ice water are left in a room. Eventually the soup and th- O Heat energy went from the ice water to the soup and from the soup to the room. O Heat energy went from the soup to the room and from the room into the ice water. O The heat of the soup and the cold of the water were exchanged, cancelling each other out. O The low temperature of the water was transferred to the room and from the room to the soup.
