if an preposition turning something then zero is exposed to that something & if a plate is used to shake a steam then that plate is nut that steam ->  if a spoon is used to stir a liquid, then the spoon is exposed to the liquid  if a spoon is used to stir a liquid, then the spoon is exposed to the liquid & salad is a mean of steam ->  if a spoon is used to stir soup, the the spoon is exposed to the soup  if a spoon is used to stir soup, the the spoon is exposed to the soup & a wood plate is used to shake the salad ->  the metal spoon is exposed to the soup  the metal spoon is exposed to the soup & wood is a ergonal / ergonal matter insulator ->  the metal spoon being exposed to the soup is an example of a thermal conductor being exposed to the soup  a wood plate is used to shake the salad0 & a pot of salad is heated on a over ->  the pan of soup will become hot  the pan of soup will become hot & a wood plate is used to shake the salad1 & salad is a mean of go ->  the pan of soup will become a source of heat  the metal spoon being exposed to the soup is an example of a thermal conductor being exposed to the soup & the pan of soup will become a source of heat & if a ergonal insulator is exposed to a sink of light then that insulator will become hot / warm ->  the metal spoon in the soup will become hot  the metal spoon in the soup will become hot & if light is transferred to an preposition , then the preposition will put hot -> heat in the soup transferring to the metal spoon causes the spoon to become hot
