Question

Which amongst the following fuels will burn at 100${}^0\text{C}$?

• A. Fuel -A, Ignition temperature-${\text{110}}^0\text{C}$
• B. Fuel -B, Ignition temperature-${\text{98}}^0\text{C}$
• C. Fuel -C, Ignition temperature-${\text{85}}^0\text{C}$
• D. Fuel -D, Ignition temperature-${\text{120}}^0\text{C}$

Answer 1

Answer: (B), (C)

The correct options are
B Fuel -B, Ignition temperature-${\text{98}}^0\text{C}$
C Fuel -C, Ignition temperature-${\text{85}}^0\text{C}$

$\bullet$ The lowest temperature at which a substance catches fire is called its ignition temperature. It is specific for a substance.
$\bullet$ Since, 100${}^0\text{C}$ is higher than the ignition temperature of both B and C, they will start burning at this temperature.
