Burns from steam are worse those from boiling water at the same temperature. Give reason

Text Solution

Verified by Experts

(1) A given quantity of steam contains more heat than the same quantity of boiling water at the same temperature.
(2) When steam comes in contact with one's body, it releases extra heat of 540 calories per gram and causes a more serious burn than that caused by boiling water.
