What best describes the energy changes associated with evaporation and boiling

1 answer:

4 0

Answer:The statement 'atoms gain energy during evaporation and boiling' BEST describes the energy changes associated with evaporation and boiling.

In a given substance (e.g., water), atoms gain energy when they obtain kinetic energy, i.e. when they gain movement.

Evaporation refers to the physical process where a liquid is converted to a gas (in this case, water).

These processes (evaporation and boiling) increase the kinetic energy of water molecules to the detriment of the potential energy.

In conclusion, the statement 'atoms gain energy during evaporation and boiling' BEST describes the energy changes associated with evaporation and boiling.

A gas that exerts a pressure of 537 torr in a container with a volume of 5.30 L will exert a pressure of 255 torr when transferr

ArbitrLikvidat [17]

Answer:- The gas needs to be transferred to a container with a volume of 11.2 L.

Solution:- From Boyle's law. "At constant temperature, Volume is inversely proportional to the pressure."

It means, the volume is decreased if the pressure is increased and vice versa.

Here, the Pressure is decreasing from 537 torr to 255 torr. So, the volume must increase and calculated by using the equation:

$P_1V_1=P_2V_2$

Where, $P_1$ is initial pressure and $P_2$ is final pressure. Similarly, $V_1$ is initial volume and $V_2$ is final volume.

Let's plug in the values in the equation:

(537 torr)(5.30 L) = (255 torr)( $V_2$ )

$V_2=(\frac{537 torr*5.30 L}{255 torr})$

$V_2$ = 11.2 L

So, the new volume of the container needs to be 11.2 L.

Suppose the data formed a line with a steeper slope. For the same change in temperature, how would the change in volume compare?

bogdanovich [222]

Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.
