At constant volume, you cool a sealed, air-filled can, and the pressure reduces by half. What happens in this situation? The num

ber of collisions per unit area doubles. The spaces between the gas molecules shrink. The temperature of the air inside reduces by half. Half of the gas leaks out.

Answer:

The correct answer to the question is

The temperature of the air inside reduces by half.

Explanation:

The relation to apply here is

(P₁×V₁)/T₁ = (P₂×V₂)/T₂

Thus we have at constant volume

P₁/T₁ = P₂/T₂

Therefore since the pressure reduces by half we have

then P₂ = 0.5 × P₁ or

P₁/T₁ = 0.5 × P₁/T₂ that is 1/T₁ = 0.5/T₂ or T₂ = 0.5 × T₁

The temperature of the air reduces by half

The above relationship is an example of Gay-Lussac's law which states that constant volume, the pressure of a given mass of gas is directly proportional to the temperature in kelvin. That is an increase in presure increases the temperature and a decrease in pressure causes an equivalent decrease in temperature

5. Why are lonic compounds good conductors of electricity?
ziro4ka [17]

Answer:

The options are unclear, however, the correct option is:

Aqueous solutions of ionic compounds cause to dissociate, hence, ions are free to conduct electricity

Explanation:

Ionic compounds are compounds formed from ions (charged atoms). For example, NaCl is an ionic compound from the following ions; Na+ (cation) and Cl- (anion). One characteristics of ionic compounds is their ability to dissociate into the ions that form them when in an aqueous solution i.e. NaCl will dissociate into Na+ and Cl- when in an aqueous solution.

These disssociated ions are free to conduct electricity, hence, making ionic compounds good conductors of electricity.
