Answer:

The volume of the gas will be 78.31 L at 1.7 °C.

Explanation:

We can find the temperature of the gas by the ideal gas law equation:

PV = nRT

Where:

n: is the number of moles

V: is the volume

T: is the temperature

R: is the gas constant = 0.082 L*atm/(K*mol)

From the initial we can find the number of moles:

n = \frac{P_{1}V_{1}}{RT_{1}} = \frac{1 atm*62.65 L}{(0.082 L*atm/K*mol)*(0 + 273)K} = 2.80 moles

Now, we can find the temperature with the final conditions:

T_{2} = \frac{P_{2}V_{2}}{nR} = \frac{612.0 mmHg*\frac{1 atm}{760 mmHg}*78.31 L}{2.80 moles*0.082 L*atm/(K*mol)} = 274.7 K

The temperature in Celsius is:

T_{2} = 274.7 - 273 = 1.7 ^{\circ} C

Therefore, the volume of the gas will be 78.31 L at 1.7 °C.

I hope it helps you!

vampirchik [111]

Answer:

C) As a gas is heated, the pressure decreases.

Explanation:

From the choices given, the statement that "as a gas is heated, the pressure decreases is false".

When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.

  • Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
  • When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
  • Thus, they take up even more space allowing volume to increase appreciably.
