43.Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:

(1) The ideal gas law involves the variables P, V, T, and R, and the constant n.

(2) Boiling is a special form of evaporation that occurs when atmospheric pressure exceeds the vapor pressure of the hot liquid.

44.Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:

(1) Water’s boiling point is much lower than expected, based on comparison with other substances, because of hydrogen bonding.

(2) In the gaseous state, disruptive forces and cohesive forces are of about the same magnitude.

(3) As liquid surface area increases, the rate of evaporation of a liquid increases because molecules encounter less external pressure.

a.All three statements are true.

b.Two of the three statements are true.

c.Only one of the statements is true.

d.None of the statements is true.
