Arun places a beaker of water on a hotplate and turns the hotplate on. The temperature in the room is 25 ºC. After the water heats to 75 ºC, she adds pieces of ice to the beaker. Which mode of transfer of heat energy occurs in the water during this experiment? Justify your answer

Thermal convection

Explanation:

When ice cubes are placed in water, ice cubes start melting. This is because water transfers its heat to ice cubes until the temperature becomes equal and the process is called "thermal Convection".

Thermal convection is the mode of transfer of heat energy that will occur when ice cubes will be added to the hot water and at the end of the experiment when both are at the same temperature, no ice cube will left.

Hence, the correct answer is "thermal convection".

the closer the planet is to the sun, the larger the gravity
