sentences: if a thermal conductor is exposed to a source of heat then that conductor may become hot0 & if a thermal conductor is exposed to a source of heat then that conductor may become hot2 ->  if a pot contains something then that pot touches that something  if a pot contains something then that pot touches that something & a pot contains water ->  the pot is touching the water  metal is a thermal energy conductor & a pot is made of metal for cooking ->  a pot is a thermal energy conductor  if a thermal conductor is exposed to a source of heat then that conductor may become hot & a stove is a source of heat ->  if a thermal conductor is exposed to a stove then that conductor may become hot  a pot is a thermal energy conductor & if a thermal conductor is exposed to a stove then that conductor may become hot ->  if a pot is exposed to a stove then that pot may become hot  if a pot is exposed to a stove then that pot may become hot & the pot is exposed to a stove ->  the pot may become hot  the pot is touching the water & the pot may become hot ->  the hot pot is touching the water  the hot pot is touching the water & if a thermal conductor is exposed to a source of heat then that conductor may become hot3 & a pot is a kind of object ->  the water will increase temperature by absorbing heat energy from the pot  heating means adding heat & boiling happens when liquids are heated above their boiling point ->  boiling happens when liquids increase heat energy above their boiling point  boiling happens when liquids increase heat energy above their boiling point & if a thermal conductor is exposed to a source of heat then that conductor may become hot1 -> if a pot contains something then that pot touches that something0: boiling happens when water increases heat energy above its boiling point  if a pot contains something then that pot touches that something0 & the water will increase temperature by absorbing heat energy from the pot -> the water will boil if heat energy absorbed from the pot is increased past the boiling point
