Pouring water on yourself and drying naturally (vs. toweling off) cools you
Bezzdna [24]

C. The water is using heat to undergo a phase change and

D. The water's latent heat of vaporization is being pulled from your body.

<u>Explanation:</u>

As per the Thermodynamics, to attain equilibrium, the heat always travel to cold and also high energy particle moving towards the lower energy side.

Here water we pour on our self getting dried naturally before we toweling off.

It is due to the water using the heat to gradually undergo a kind of phase change and also the latent heat of vaporization is being pulled from our body.

Question #6a) You were told to assume that the ball bounced to a height of 1.2 m and that the distance between the bounces measu
Inessa [10]

Answer:

Explanation:

In the problem they give the case of a ball that bounces on the vertical axis the height is getting smaller, on the x axis it is the same distance all the time.

Questions about the aspect of the x-axis

- Since the distance traveled between the rebounds is the same, the speed must be the same or constant throughout the entire journey.

- Since the distance and speed are equal, the time between rebounds is the same

- There can be no acceleration because the bounce gap should change, the acceleration is zero all the time

Questions about the Y axis

- The vertical speed of the first boat would be the greatest of all, so it has the highest height

b) Evidence or not Evidence

1  evidence, because the graphs are different, one is a straight line and he gives a parable

2 no evidence, nothing involved on the x axis

3  no evidence, the acceleration on the y axis is independent of the acceleration on the x axis

4  no evidence, the time that is cast is the only change that is the same for both movements

5  evidence, the fact that no mixture of components is found allows the variable to be separated into different equations

6  no evidence, says nothing about the x-axis

Ocean water has a salinity of 35 parts per thousand. Fresh water has a salinity of less than 0.5 parts per thousand. What can yo
Scrat [10]

A is correct since there is an abundance of salt minerals/salt in the ocean water that causes to be quite considerably salty.

A salinity of 35 parts per thousands is 3.5% of a thousand. That means for every litre of of seawater, there is 35 grams of salt most dissolved in it.

Also, the salinity of the ocean does stagnate around 3.5% but in some parts of the world, it depends on where it is located, and the salinity might be higher and others parts may be much lower. Therefore B is incorrect as it doesn't vary considerably.

Freshwater does contain a very very tiny amount of salt and that indicates that freshwater containing no salt at all is a false statement.

Lastly, most of the salt in ocean water is not magnesium since most of salt in ocean water is sodium but magnesium is the second most commonly found cation in oceans. Freshwater contains very little magnesium while the oceanic marine bodies do.

For example: rivers contain upwards of 4ppm of magnesium while marine algae can contain from between 6,000 to 20,000 ppm of magnesium.
