CHEM 1770 Unit E Terms

Endothermic

Describes a process that absorbs heat from its surroundings.

Energy

The capability to do work.

Systematic errors

Error that tends toward being consistently either too high or too low.

Kinetic Energy

The energy associated with the motion of an object.

Thermal Energy

The type of kinetic energy associated with the temperature of an object, arising from the motion of individual atoms or molecules in the object: see also heat.

Intensive property

A property such as density that is independent of the amount of a given substance.

Density

The ratio of an object's mass to its volume.

Exothermic

Describes a process that releases heat to its surroundings.

Random Error

 Error that has equal probability of being too high or too low.

Potential Energy

The energy associated with the position or composition or composition of an object.

Work

The result of a force acting through a distance.

Volume

A measure of space. Any unit of length when cubed (raised to the third power) becomes a unit of volume.

Law of conservation of energy

The law stating that energy can neither be created nor destroyed, only converted from one form to another.

Precision

A term that refers to how close a series of measurements are to one another or how reproducible they are.

Extensive property

A property that depends on the amount of given substance such as mass.
