Flammable substances are materials that can catch fire and burn when exposed to an ignition source. They can be in solid, liquid, or gas form and produce vapors that mix with air, making them susceptible to ignition. Key characteristics include the flash point (temperature at which vapors ignite), auto-ignition temperature (spontaneous ignition), and flammability limits (the vapor concentration range that can ignite).

Examples include liquids like gasoline and ethanol, gases like hydrogen, and solids like magnesium. Proper handling and storage are crucial to avoid fire hazards.

A flammable substance is a material that easily catches fire when exposed to heat, sparks, or an open flame. It has a low ignition temperature and burns quickly, increasing the risk of fire hazards. Examples include gasoline, alcohol, and propane. Safe handling and storage are essential to prevent accidents.

Hello Rohit,

An inflammable substance is a material that catches fire easily and burns rapidly. These substances have low ignition points and can ignite with a small spark or heat source.

Examples:

• Petrol
• Alcohol
• Kerosene
• LPG (Liquefied Petroleum Gas)
• Hydrogen gas

Note: Inflammable and flammable mean the same thing—both refer to substances that can catch fire easily.
