Question

The table below shows the ignition temperatures of four solid fuels.
$$\begin{array}{cc}\text{Fuels}& \text{Temperature (}{}^{\circ }\text{C)}\\ \text{P}& \text{300}\\ \text{Q}& \text{55}\\ \text{R}& \text{130}\\ \text{S}& \text{500}\end{array}$$

Based on the given information, identify the solid fuel that will catch fire easily.

• A. S
• B. R
• C. Q
• D. P

Answer 1

The correct option is C Q

Ignition temperature is the minimum temperature at which a substance catches fire. A substance with lower ignition temperature will catch fire easily than the ones with a higher ignition temperature.

Thus, out of the given solid fuels, Q with the lowest ignition temperature will catch fire easily.
