Power Words

density A measure of the compactness of a substance. Density is equal to the amount of mass per unit of volume. In general, density increases as pressure increases and temperature decreases.

germination The sprouting of a seed, spore, or bud. Germination usually takes place in the spring, when climate and soil are warm and moist.

volume 1. The amount of space that is filled by an object. Volume is measured in cubic units, such as cubic feet or cubic meters, and includes the number of feet or meters that make up the length, the height, and the depth of an object. 2. The loudness of a sound. The higher the volume is, the louder the sound is.
