Question | Answer |
biohazard | A living organism or its by-product that is harmful to the health of humans or other living things. For example, human blood is considered a biohazard because it can transmit infectious diseases. |
clear | Transparent or see-through. A clear substance can be either colored, like food coloring, or colorless, like water. |
colorless | Having no color. |
corrosive | The ability of a substance to dissolve or wear away other substances, such as metals or human tissue. Strong acids and bases are corrosive. |
density | The relationship between mass and volume of a substance; the mass per unit volume, specifically grams per milliliter. Density equals mass divided by volume (d = m/v) |
evidence | Information that is gained by direct observation or from reliable sources which can be used to inform decision making. |
flame test | A method of identifying a substance. A flame test is typically conducted by placing a small amount of the substance to be tested on the end of a looped metal wire and holding the looped end in the center of a flame. |
flammable | Easily ignited. |
HAZMAT team | An abbreviation for a hazardous materials team; a group of individuals who have the skills needed to investigate, identify, and transport hazardous materials. |
hazardous | Harmful to the health of humans or other living things because of toxicity, flammability, corrosiveness, reactivity, radioactivity, or infectiousness. |
indicator | A substance that changes color in the presence of another chemical or group of chemicals. For example, universal indicator is an acid-base indicator that shows by color the pH of a substance. |
infer | To conclude by reasoning from evidence. For example, if we see a child running toward a school building in the morning as the bell rings, we can infer that the child is late for school. |
miscible | The ability of substances (usually liquids) to mix together. For example, milk and water are miscible, whereas oil and water are not. |
mixture | A physical combination of two or more substances. Mixtures do not usually have a fixed composition: the amount of one or more of the substances in the combination can vary. |
MSDS | An abbreviation for Material Safety Data Sheet, which is a list of the chemical and physical properties of a specific chemical. |
observe | To see or otherwise detect something. |
oxidizer | A substance that readily accepts electrons from another substance, often resulting in combustion. Oxygen is an example of an oxidizer. |
pH | The expression of the acidic or basic strength of a solution. (see rest of definition on hard copy) number representing a ten-fold increase in hydrogen ion concentration; 14 is the least acidic (or most basic), 7 is the neutral and 1 is th |
phase | A homogeneous state of matter; either solid, liquid, or gas. |
physical property | An intrinsic property of a material, such as density, melting point, or hardness |
radioactive | Capable of releasing energy in the form of particles or electromagnetic waves. |
reactive | Capable of exploding when exposed to other substances (such as air or water) or emitting toxic fumes when mixed with other substances. |
simulation | A model or example of a real-life situation or event. |
solubility | A measure of the amount of a substance that will dissolve in a specified amount of another substance at a particular temperature. Often measured in grams per liter at 25˚ C. |
toxic | Poisonous; the capability of a substance to cause harm to living systems. |
