Burning with hot liquid is a process known as scalding (5 letters) and is often done with LAVA (4 letters). Scalding is a cooking technique used to heat food or liquids to a specific temperature. It is commonly used to prepare meats, vegetables, and other foods. LAVA is molten rock that is expelled from a volcano during an eruption. It is extremely hot and can reach temperatures of up to 1, 200 degrees Celsius. When LAVA comes into contact with water, it can cause a violent reaction that can result in the burning of anything in its path.
