Answer:
- <u>Compressibility, expandibility, and density, are the most conspicuous properties of the gases explained by </u><em><u>the assumption that most of the volume in a gas is empty space.</u></em>
Explanation:
One of the assumptions of the kinetic molecular theory is that the gas particles are way smaller than the separtion between them and, in consequence, most of the volume in a gas is empty space.
This condition (that most of the volume in a gas is empty space) explains why the gases can be easily compressed: since there are vast unoccupied spaces when the pressure is increased, the particles can approach each other with which the total volume of the gas decreases.
Expandibility, the property of expanding, is the ability that gases have to occupy the entire space of the container in which they are located. The particles then will get separated leaving most of the space empty.
The fact that most of the volume in a gas is empty space means that the volume for a certain amount of particles is much larger than the volume that the same number of particles in a solid will occupy, driving to much lower densities.
Answer:
mammals are the animal who lay eggs
Answer:
λ = 0. 484 × 10⁻⁸ m
Explanation:
Given data:
Frequency = 6.2 × 10¹⁶ Hz
Wavelength = ?
Solution:
Formula:
Wavelength = speed of light / frequency
speed of light = 3 ×10⁸ m/s
λ = c / f
λ = 3 ×10⁸ m/s / 6.2 × 10¹⁶ s⁻¹
λ = 0. 484 × 10⁻⁸ m
Answer:
Explanation:
¡Hola!
En este caso, para los problemas de equilibrio térmico, consideramos que la energía liberada por la sustancia que inicialmente está caliente (agua), es absorbida por la sustancia que inicialmente está fría (alcohol); thus, we can write:
La cual puede ser escrita en términos de masa, calor specifico y temperaturas:
De este modo, al resolver para la temperature de equilibrio térmico, obtenemos la siguiente expresión:
Así, al reemplazar los valores en esta, obtenemos:
¡Saludos!
Can you explain the question further?
