A 1.87 mol sample of Ar gas is confined in a 45.5 liter container at 23.6 °C.
lora16 [44]

Answer:

a. increase

Explanation:

Based on the kinetic molecular theory of gases, the average kinetic energy of the system will increase.

  • The average kinetic energy is heat
  • If temperature increases, heat of a system will also rise.
  • According the kinetic molecular theory "the temperature of the gas is a measure of the average kinetic energy of the molecules"

Therefore, due to the increase in temperature, the average kinetic energy of the system increases.

Question 5 (1 point)
Aleksandr-060686 [28]

Answer : The pressure it exert under these new conditions will be, 87 atm

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 19 atm

P_2 = final pressure of gas = ?

V_1 = initial volume of gas = 100 L

V_2 = final volume of gas = 20 L

T_1 = initial temperature of gas = 25^oC=273+25=298K

T_2 = final temperature of gas = 0^oC=273+0=273K

Now put all the given values in the above equation, we get:

\frac{19atm\times 100L}{298K}=\frac{P_2\times 20L}{273K}

P_2=87atm

Therefore, the pressure it exert under these new conditions will be, 87 atm

Last week at a tax free sale, Ms. Kuhn bought 4 shirts for $15.95 each and 2 new belts
erastovalidia [21]

Answer:

$18.30

Explanation:

The change is the amount left over after the selling price has been matched by the buyer.

Let us find the total cost of what of Ms. Kuhn bought;

For the shirt;

    Cost  = 4 shirts for $15.95 each  = 4(15.95) = $63.8

                2 new belts for $8.95 each  = 2(8.95)  = $17.9

Total cost  = $63.8 + $17.9  = $81.7

The amount of change left  = $100  - $81.7  = $18.3
