Sakshi took a piece of four substances W, X ,Y and Z .She tried to burn each of them by bringing a lighted matchstick near them. She observed that Y and Z burns readily where as W burns readily only after sustained heating however X does not burn at all .Among the given substance taken by Sakshi, which substance has the highest ignition temperature 1 point a. W b. X c. Y d. Z
Answers
Answer:
Correct Answer: B Solution
Explanation:
The ignition temperature of a substance is the lowest temperature at which a substance catches fire. On bringing a lighted matchstick near the substances
W, X, Y, and Z, the ignition temperature of X is not reached. However, the ignition temperature of W, Y, and Z are reached. Hence, while X does not burn, W, Y, and Z burn readily. Thus, the ignition temperature of X would be the highest among the substances taken by Sakshi. The correct answer is B.
