A gas is allowed to expand from a volume of 400 ml to 2000 ml at a constant temperature. If the the initial pressure is 3 atm, c
Lostsunrise [7]

Answer:

P_{2}) = 0.6 \; atm

Explanation:

<u>Given the following data;</u>

Initial volume = 400 mL

Final volume = 2000 mL

Initial pressure = 3 atm

To find the final pressure P2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

3 * 400 = P_{2}* 2000

1200 = 2000P_{2}

P_{2}) = \frac {1200}{2000}

P_{2}) = 0.6 \; atm

Answer:

Sal, cobre, aluminio, anillo de oro puro Oxígeno ------ suspensión.

Cerveza, carbonato de sodio, oxígeno, carbono y helio ------ solución.

Explicación:

Sal, Cobre, Aluminio, Anillo de oro puro Oxígeno son los ejemplos de suspensión porque permanecen suspendidos en la solución mientras que por otro lado, Cerveza, Carbonato de sodio, Oxígeno, Carbono y helio son los ejemplos de solución porque formaron una mezcla homogénea en la que ambas soluciones no se pueden diferenciar entre sí pero en suspensión sí se pueden diferenciar.
