Independent Variable here is ”Speed”, since the independent variable is defined as (what's the scientist changes or what changes on its own)... And in here, both cars were traveling at 60 mph ’at a certain point, so, one of them might speed up or stay behind/lower it's speed from the other, depending on it's driver’.
Dependent Variable here is ”Distance”, since the dependant variable is defined as (what s being studied/measured).
Speed = distance/time
=> speed = 817/19 m/sec = 43 m/sec
hope it helps!
Answer:
That's true. What are you asking?
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:
Heres a very LONG answer-
The real answer:
Its in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.
