Characterize the effect that changes will have on the vapor pressure (v. p.) and boiling point (b. p.) of a liquid by increasing the external pressure on the surface of a liquid at constant temperature. Group of answer choices v. p. does not change, b. p. decreases v. p. decreases, b. p. decreases v. p. does not change, b. p. increases v. p. decreases, b. p. does not change
