When a substance easily dissolves in a liquid, it has high solubility in that liquid. When a substance does not easily dissolve

in a liquid, it has low solubility in that liquid. Solubility of a gas in water describes how well the liquid can "hang on" to gas, instead of releasing it into the air. Based on the results of your experiment, do you think that CO2 has a higher solubility in hot water or cold water? Why?

Answer:

CO2 has a higher solubility in cold water

Explanation:

The solubility of gases decreases with increasing temperature,  the cold water will take up more CO2 and less will be escaping to the air. Furthermore, cold water is denser than warm water, causing it to sink.

A professor, with dumbbells in his hands and holding his arms out, is spinning on a turntable with an angular velocity. What hap
Olenka [21]

Answer:

<em>His angular velocity will increase.</em>

Explanation:

According to the conservation of rotational momentum, the initial angular momentum of a system must be equal to the final angular momentum of the system.

The angular momentum of a system = I'ω'

where

I' is the initial rotational inertia

ω' is the initial angular velocity

the rotational inertia = mr'^{2}

where m is the mass of the system

and r' is the initial radius of rotation

Note that the professor does not change his position about the axis of rotation, so we are working relative to the dumbbells.

we can see that with the mass of the dumbbells remaining constant, if we reduce the radius of rotation of the dumbbells to r, the rotational inertia will reduce to I.

From

I'ω' = Iω

since I is now reduced, ω will be greater than ω'

therefore, the angular velocity increases.
