What is pressure in relation to a gas?

Chemistry
1 answer:
labwork [276]2 years ago
7 0

The pressure of a gas is the force that a gas exerts per unit area of the container.

Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.

Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.

The volume of a container refers the size if the container.

The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.

For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.

For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.

Buffers resist change in pH in a system when?
Sedbober [7]
The answer to this question is <span>b) hydrogen chloride (HCl) is added to the system. This is the only acid/base on the list. Only acids and bases have the potential to directly change pH as they contribute hydronium and hydroxide ions. Glucose, sodium chloride, and sodium bromide do not affect pH in the first place.</span>

snow_tiger [21]

Answer:

7.45\times 10^{26} photons are emitted per second in a 1\times 10^3 Watt microwave oven.

Explanation:

The expression for the power is:-

Power=\frac{Energy}{Time}

Also, E=n\times \frac{h\times c}{\lambda}

Where,  

n = the number of photons

h =  Plank's constant having value 6.626\times 10^{-34}\ Js

c =  the speed of light having value 3\times 10^8\ m/s

\lambda = the wavelength of the light

So,  

Power=\frac{n}{Time}\times \frac{h\times c}{\lambda}

Thus, the expression for photons per second is:-

\frac{n}{Time}=\frac{Power\times \lambda}{h\times c}

Given that:-

Power = 10³ Watt

( 1 cm = 0.01 m)

[/tex]

So,  

Photon/sec=\frac{10^{3}\times 0.148}{6.626\times 10^{-34}\times 3\times 10^8}=7.45\times 10^{26}

7.45\times 10^{26} photons are emitted per second in a 1\times 10^3 Watt microwave oven.
