The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.

<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
In a gas, the partcles are very far apart and loose.
