Why does isopropyl alcohol burn when it comes into contact with an open flame?
Isopropyl alcohol burns when it touches an open flame because it is a flammable substance that easily ignites when exposed to heat.
Why are covalent compounds more dangerous near an open flame?
Covalent compounds tend to be more volatile and flammable compared to ionic compounds. When exposed to an open flame, covalent compounds can easily vaporize and form combustible mixtures with air, leading to flammable or explosive reactions. This increased reactivity near an open flame makes covalent compounds more dangerous in such conditions.
Is the hole open or closed on a Bunsen burner to make a safety flame?
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
The process of combustion occurring without an open flame is called?
The process of combustion occurring without an open flame is called spontaneous combustion. This phenomenon usually happens when a material self-heats to its ignition temperature without an external heat source.
What do you call an air hole open flame on an bunson burner?
An open flame above an air hole on a Bunsen burner is called a roaring flame. It occurs when the air hole is fully open and allows for more oxygen to mix with the gas, creating a hotter and louder flame. Adjusting the air hole can help control the flame temperature and intensity.
Why does isopropyl alcohol burn when it comes into contact with an open flame?
Isopropyl alcohol burns when it touches an open flame because it is a flammable substance that easily ignites when exposed to heat.
Why should CFC-12 never be exposed to a open flame?
CFC-12 is a chlorofluorocarbon compound that can decompose when exposed to high temperatures, producing toxic byproducts like phosgene gas. Phosgene gas is highly toxic and can pose serious health risks when inhaled. Therefore, exposing CFC-12 to an open flame can lead to the formation of phosgene gas, which is dangerous to human health.

What is considered an open fire?
An "open flame" refers to flame, usually used as a heating source, that is directly exposed to the outside elements, or often the object to be heated. Examples would include a Bunsen burner, a bonfire, or in some cases grills. The opposite would include heating elements that do not directly openly expose the flame, such as old stoves or heating elements.
Is the air hole opened for a roaring flame?
A roaring flame indicates that the air inlet is open too far and should be closed slightly.
What is flash point of glycerin?
The flash point of glycerin is approximately 160°C (320°F). This is the temperature at which glycerin can ignite if exposed to an open flame or heat source.
How can you make fire with glycarin?
Glycerin can be used to make fire by mixing it with Potassium Permanganate. The mixture is the exposed to an open flame where it will quickly ignite and burn at high temperatures.
How flammable is pine-sol?
Pine-Sol is a flammable liquid. It can ignite if exposed to an open flame or heat source. It is important to keep Pine-Sol away from heat sources or open flames to prevent fire hazards.
Is the hole open or closed on a Bunsen burner to make a safety flame?
The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.
When should the flame of a Bunsen burner with the collar open be used?
When you want to heat something!! well wen it is closed is when it is at its hottest, its a heating flame, open is for safety that's when it is at its coolest like a safety flame. what i rote when you want to heat something is rong at the top. that's for if it is closed
The voltage generated b y a thermocouple in a pilot flame should be?
30 MV open circuit
