The warm air over the beach rises while the cooler denser air rushes in due to the transfer of heat through the air by the convection process.
Thus, convection is the correct answer to the 9th question.
The heat travels from the marshmallow to the screwdriver which is in contact with the marshmallow. This process is the conduction process.
Thus, conduction is the correct answer to the 10th question.
The hair curler transfers the heat to the hair which is in contact with the curler.
This process of transfer of heat is known as the conduction process.
Thus, conduction is the correct answer to the 11th question.
The body of the person is in contact with the rock. Thus, the transfer of heat takes place due to conduction.
Thus, conduction is the correct answer to the 12th question.
