Convection when heat travels through metal or appliances.

Explanation:

Universal pH paper turns red if it is very strongly acidic, turns orange if it is strongly acidic, turns yellow if it is weakly acidic, green if it is weakly alkali and blue if it is strongly alkali.

Solution A will turn orange as it is strongly acidic

Solution B will turn blue as it is strongly alkali

Solution C will turn yellowish green as it is neutral
