Temperature
Definition:
(n.) Constitution; state; degree of any quality.
(n.) Freedom from passion; moderation.
(n.) Condition with respect to heat or cold, especially as indicated by the sensation produced, or by the thermometer or pyrometer; degree of heat or cold; as, the temperature of the air; high temperature; low temperature; temperature of freezing or of boiling.
(n.) Mixture; compound.
Example Sentences:
