Red Helmet Master Flashcards
Acid
A substance that donates protons or hydrogen ions and/or accepts electrons.
Example: Hydrochloric acid (HCl) is a strong acid.
Base
A substance that accepts protons or hydrogen ions and/or donates electrons.
Example: Sodium hydroxide (NaOH) is a strong base.
Caustic
A substance that can cause damage to living tissue or severe corrosion.
Example: Caustic soda is another name for sodium hydroxide.
Air reactive
Substances that react with air, often releasing heat or producing hazardous byproducts.
Auto refrigeration
A process where a substance cools itself as it expands or vaporizes.
Biological agents
Microorganisms or toxins that can cause disease in living organisms.
Blood agents
Toxic substances that affect the body’s ability to transport oxygen.
Boiling point
The temperature at which a liquid turns into vapor.
Catalyst
A substance that increases the rate of a chemical reaction without being consumed.
Chemical change
A process where substances transform into different substances.
Chemical interaction
The process by which substances combine or react with each other.
Compound mixture
A combination of two or more substances that retain their individual properties.
Concentration
The amount of a substance in a given volume of solution.
Critical temperature for gases
The temperature above which a gas cannot be liquefied by pressure.
Critical pressure for gases
The minimum pressure required to liquefy a gas at its critical temperature.
Dissociation for atoms
The process by which atoms or molecules separate into smaller particles.
Corrosivity
The ability of a substance to damage or destroy materials, especially metals.
Dose for exposure
The amount of a substance that an organism is exposed to.
Dose rate for exposure
The amount of a substance an organism is exposed to over a specific period.
Dose response for exposure
The relationship between the dose of a substance and the magnitude of its effect.
Expansion ratio
The ratio of the volume of a gas to its volume in a liquid state.
Flash point
The lowest temperature at which a liquid can form an ignitable mixture in air.
Fire point
The temperature at which a liquid produces enough vapor to sustain combustion.
