Burning logs in the fire place produce heat energy. The dog gets warm from the fire when heat energy is transferred by A) the air. B) radiation. C) conduction. D) the flames.

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
