It is generally recommended to leave the solar cover on during the day to help absorb and retain heat in the pool. This will help maximize the effectiveness of the cover in maintaining warm water temperatures.

The escape velocity from Earth is greater for larger rockets than for small ones?

Escape velocity from Earth depends only on the mass of the Earth and the distance from its center, not the mass or size of the rocket. All rockets need to reach the same escape velocity to leave Earth's gravitational pull, regardless of their size.


How can one determine how to find escape velocity in a given scenario?

To find escape velocity in a given scenario, you can use the formula: escape velocity square root of (2 gravitational constant mass of the planet / radius of the planet). This formula takes into account the gravitational pull of the planet and the mass and radius of the planet. By plugging in these values, you can calculate the escape velocity needed to leave the planet's gravitational pull.


What happens when high energy particles leave the surface of the liquid?

When high energy particles leave the surface of a liquid, it causes the liquid to evaporate. Evaporation occurs when molecules at the surface gain enough energy to escape into the air as gas.


Use the kinetic theory to explain evaporation?

In the kinetic theory, evaporation occurs when the molecules of a liquid gain enough kinetic energy to escape the attractive forces of neighboring molecules and enter the gas phase. As the liquid molecules absorb heat from their surroundings, they move faster and collide with greater force, increasing the likelihood of breaking free. This process leads to the liquid's overall cooling, as the higher-energy molecules leave, resulting in evaporation.


Why is the water left behind during evaporation cool?

This can be understood in different ways. 1) Evaporating is a change of phase which costs energy. This energy is taken from the heat energy of the water. 2) Only the fastest molecules in the water evaporate, leaving behind molecules that are, on average, slower and therefore colder. The fast molecules that leave the water also slow down, due to the attractive forces from the molecules they leave behind; thus, the vapor will also cool down.
