The partial pressure of cartbon dioxide in the atmgsphere is 0239 toer Caiculate the partial pressure in mm He and atm Rpund eac
Verizon [17]

Answer :

The pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.

The pressure of carbon dioxide in the atmosphere in atm is 3.14\times 10^{-4}atm.

Explanation :

The conversion used for pressure from torr to mmHg is:

1 torr = 1 mmHg

The conversion used pressure from torr to atm is:

1 atm = 760 torr

or,

1torr=\frac{1}{760}atm

As we are given the pressure of carbon dioxide in the atmosphere 0.239 torr. Now we have to determine the pressure of carbon dioxide in the atmosphere in mmHg and atm.

<u>Pressure in mmHg :</u>

As, 1torr=1mmHg

So, 0.239torr=\frac{0.239torr}{1torr}\times 1mmHg=0.239mmHg

Thus, the pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.

<u>Pressure in atm:</u>

As, 1torr=\frac{1}{760}atm

So, 0.239torr=\frac{0.239torr}{1torr}\times \frac{1}{760}atm=3.14\times 10^{-4}atm

Thus, the pressure of carbon dioxide in the atmosphere in atm is 3.14\times 10^{-4}atm.

A substance conducts electricity because of free moving, charged particles.
Galina-37 [17]

Answer:

105Comprendes las leyes de la electricidadAprende másClasificación de los materialesUn medio o material que permite el movimiento de las cargas eléctricas (electrones) en respuesta a una fuerza eléctrica, se denomina conductor. Los materiales conductores son los que se pueden electrizar en toda su superficie, debido a que los electrones se mueven libremente. Los metales por lo general son buenos conductores de la electricidad.El flujo de las partículas cargadas es lo que se conoce como corriente eléctrica. Las partículas cargadas en una cierta dirección de un conductor chocan con los átomos, produciendo una pérdida de energía que se manifiesta en forma de calor.Una medida de oposición que presentan las partículas cargadas al moverse libre-mente en una cierta dirección de un material conductor es lo que se conoce como resistencia eléctrica.Los materiales que no permiten que las partículas cargadas se muevan hacia otra región del material a una fuerza eléctrica, son llamados aislantespor ejemplo, la madera.Existen otros tipos de materiales cuyas propiedades son intermedias entre los conductores y aislantes; se llaman semiconductores.Algunos ejemplos de materiales con estas características son:
