What is the flashpoint for alcohol?
The flash point of pure ethanol is 13 °C (55 °F), but may be influenced very slightly by atmospheric composition such as pressure and humidity. Ethanol mixtures can ignite below average room temperature.
How do you find the flash point of a mixture?
Flash points are determined experimentally by heating the liquid in a container and then introducing a small flame just above the liquid surface. The temperature at which there is a flash/ignition is recorded as the flash point.
What is the flashpoint of 70% alcohol?
Flash Point: 17°C (63°F) CC.
What is the flash point of ethanol and what does it mean?
Answer: The flash point of 200 proof ethyl alcohol is 14 °C or 57.2 °F. MrTincture Says: The flash point is the temperature at which point the flammable chemical compound gives off sufficient vapors to ignite in air. When the chemical compound is below the flash point, no flammable vapors are released.
What is the flash point of 190 proof alcohol?
FLASH POINT: 60° F ASTM D-56 (Tag Closed Cup) AUTO-IGNITION TEMPERATURE: 685° F FLAMMABLE LIMITS IN AIR, % BY VOLUME: LOWER: 3.3 UPPER: 19 NFPA (National Fire Protection Association) RATING: HEALTH (0) FIRE (3) REACTIVITY (0) (Does not apply to exposure hazards other than during a fire.)
What is the flash point of water?
By definition, any liquid with a flashpoint less than 100°F is considered to be a flammable liquid….Flash Point.

| ethyl ether | 35 | -45 |
| ethanol (absolute) | 78 | 12 |
What does flash point mean?
The flash point is an important concept in fire investigation and fire protection because it is the lowest temperature at which a risk of fire exists with a given liquid. It is crucial in many circumstances to establish the presence of some liquids and to know their flash point during the investigation process.

What do you mean by flash point?
flash point, the lowest temperature at which a liquid (usually a petroleum product) will form a vapour in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame. The flash point is a general indication of the flammability or combustibility of a liquid.
