The correct option is both conduction and convention
Explanation:
- Conduction can simply be described as the transfer of heat from a hot object to a cooler one. As the container P became hot due to the metal block, it conducted its heat to the container Q.
- As the container Q became hot, it melted the ice due to absorption of heat. As a result, the water became cooler sue to ice melting and heat was taken from the atmosphere.
- In this way, the temperature was stabilized.
