Question

Four substances A,B,C and D have their ignition temperature of ${60}^{0}C,{55}^{0}C,{25}^{0}C\mathrm{and}{20}^{0}C$ respectively. It is in the increasing order of inflammability of the given substances.

Why does Substance D have the highest inflammability among all the substances?

• A. Higher the ignition temperature, Higher the Inflammability
• B. Lower the ignition temperature, lower the inflammability
• C. Lower the ignition temperature , higher the inflammability
• D. Higher the ignition temperature, Lower the inflammability

Answer 1

The correct option is C

Lower the ignition temperature , higher the inflammability

A substance that has very low ignition temperature and can easily catch fire with a flame is called an inflammable substance.
