sentences: if a spoon is used to stir a liquid then that spoon is touching that liquid & if a spoon is used to stir a liquid then that spoon is touching that liquid2 ->  if a spoon is used to stir soup then that spoon is touching that soup  if a spoon is used to stir soup then that spoon is touching that soup & the spoon is used to stir soup ->  the spoon is touching the soup  if a spoon is used to stir a liquid then that spoon is touching that liquid0 & the soup is cooking on the stove ->  heat energy is added to the soup  the spoon is touching the soup & heat energy is added to the soup ->  heat energy is added to soup that is touching the spoon  soup is a kind of thing & a spoon is a kind of thing ->  soup and a spoon are kinds of things  soup and a spoon are kinds of things & if two things are touching then heat energy will be transferred between those things ->  if soup and a spoon are touching then heat energy will be transferred between the soup and spoon  heat energy is added to soup that is touching the spoon & if soup and a spoon are touching then heat energy will be transferred between the soup and spoon ->  heat energy is transferring from the soup to the spoon  heat energy is transferring from the soup to the spoon & the spoon in the example is made of wood ->  heat energy is transferring from the soup to wood  a thermal insulator slows the transfer of heat & wood is an thermal insulator ->  wood can slow the transferring of the heat  heat energy is transferring from the soup to wood & wood can slow the transferring of the heat -> if a spoon is used to stir soup then that spoon is touching that soup0: the transferring of heat energy from soup to wood is slowed down  if a spoon is used to stir soup then that spoon is touching that soup0 & if a spoon is used to stir a liquid then that spoon is touching that liquid1 -> the wood will increase temperature slower
