Is carbonate flammable?
No, carbonate is not flammable because it does not contain any combustible materials. When heated, carbonate compounds may decompose and release carbon dioxide, but they do not catch fire.
What is minimum concentration of alcohol in water that is flammable?
The minimum concentration of alcohol in water that is flammable typically starts around 50% alcohol by volume (ABV) for ethanol. At this concentration, the mixture can produce enough vapor to ignite when exposed to an open flame or spark. However, lower concentrations can also be flammable under certain conditions, particularly if the mixture is heated or if the vapor concentration is high enough. Always exercise caution when working with flammable substances.
What do substances do when heated because of the molecules?
they expand
Do substances have to contain water in order to be heated in the microwave?
No, substances do not have to contain water to be heated in the microwave. The microwave oven uses electromagnetic waves to agitate the molecules in the substance being heated, causing them to generate heat regardless of their water content.
How does the sunlight warm the land air and water?
Land and sea are heated by absorbing radiant energy from the sun. Air is heated indirectly by being in contact (conduction) with land or water.
What do Metals and other substances do when heated?
materials usually expand when heated.
What expands when its heated?
Most substances expand when heated.
Are bottles flammable?
Most are combustible (they will burn if heated sufficiently)

Is shaving cream flammable?
The cream isn't flammable, but the canister is, if heated up. This holds true for most objects that are stored in pressurized canisters.
What is the difference between a calorifier and a chlorifier?
A calorifier is a sealed tank, which heats water indirectly. Usually in the form of a heated coil which is immersed in the water. Commonly known as a hot water tank. A chlorifier is a water tank in which the water is heated via an external source.
What do substances do when heated because of the molecules?
they expand
Why are substances expanded when they are heated?
because the particles
Why substances often expand when they are heated?
because the particles
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
Why is solid naphthalene not heated directly with a Bunsen burner?
Solid naphthalene is not heated directly with a Bunsen burner because it can undergo sublimation, meaning it can turn directly from a solid to a gas without passing through the liquid phase. This process can lead to the rapid vaporization and combustion of naphthalene, increasing the risk of fire or explosion.
