Which kind of injuries result from the deliberate act of a child having their hand placed in hot liquid?

Scald injuries occur when skin is exposed to hot liquids, such as water, oil, or other fluids. In the scenario described, where a child's hand is deliberately placed in hot liquid, the primary mechanism of injury is the exposure to the high temperature of the liquid, which can result in burns. Scald injuries typically manifest as red or blistered skin, reflecting the severity and depth of the burn caused by the hot liquid.

This type of injury is particularly relevant in this context because it explicitly involves the contact of skin with heated liquids, aligning directly with the definition of scalding. Other types of injuries, like friction, splash, or spill, relate to different causes and mechanisms and do not accurately capture the nature of burns resulting from direct contact with hot liquids.
