How does the properties of matter in liquid and gas state allow the Herons fountain to work?
Varvara68 [4.7K]

Answer:

Heron's fountain is an hydraulic machine that works because or the pressure inside of the system. Water will flow from high gravitational potential energy to low gravitational potential energy. The two sides of the system will present different pressure because they have different fluids in it (water and air) and  water pressure is higher than gas/air pressure, so it will flow.

It is important to take into account that the pressure in the columns is a function of the height of the fluid (water or air).

Explanation:

<u>The properties of liquid:</u>

- If a liquid is poured into a container, it will adapt to the container's shape

- In a liquid state, the molecules have a kinetic energy higher than in a solid state

- Liquid particles are not arranged in a regular way but they are very close  to each other, that's why liquids have a definite volume.

- Force is spread in an even way through a liquid, so the liquid particles are displaced if an object is placed in it.

- Liquids, as solids, can't be compressed

<u>The properies of gas:</u>

- They are everywhere

- Gas molecules are disorganized and have a great deal of space between them

- Gas fill up any container and spread indefinitely

- Gas molecules have a high kinetic energy

- If gas is put under pressure, the space between particles will decrease and collisions between them will increase.

- If the temperature of the gas increases in a container, the pressure will increase; if the temperature decreases, the pressure sill decrease.

- It can be compressed

- Gas has no definite volume nor definite shape.

Identify each of the following sets of quantum numbers as allowed or not allowed in the hydrogen atom.
Westkost [7]

Answer:

See explanation.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to firstly recall the electron configuration of hydrogen:

1s^1

To realize that the principal quantum number is 1, the angular is 0 as well as the magnetic one; therefore we infer that all the given n's are not allowed, just l=0 is allowed as well as ml=0 yet the rest, are not allowed.

Best regards!

!!!!!PLEASE HELP!!!!!
ollegr [7]

Answer:

Difference in the potential energy of the reactants and products

Explanation:

 

The products have a lower potential energy than the reactants, and the sign of ΔH is negative. In an endothermic reaction, energy is absorbed. The products have a higher potential energy than the reactants, and the sign of ΔH is positive.

Which substance is a base? HCOOH RbOH H2CO3 NaNO3
Alex Ar [27]

Answer:

RbOH

Explanation:

For this question, we have to remember what is the definition of a base. A base is a compound that has the <u>ability to produce hydroxyl ions</u> OH^-, so:

AOH~->~A^+~+~OH^-

With this in mind we can write the <u>reaction for each substance:</u>

HCOOH~->~HCOO^-~+~H^+

RbOH~->~Rb^+~+~OH^-

H_2CO_3~->~CO_3^-^2~+~2H^+

NaNO_3~->~Na^+~+~NO_3^-

The only compound that fits with the definition is RbOH, so this is our <u>base</u>.

I hope it helps!
