Answer: Diagram 4
Explanation: Diagram 1 represents a state in which particles are closely packed , thus cannot be a representation of gas.
Diagram 2 represents a state in which particles are loosely packed , thus can be a representation of gas.
Diagram 3 represents a state in which particles are closely packed , thus can be a representation of a solid.
Diagram 4 represents a state in which particles are loosely packed , thus can be a representation of gas. It also represents the particles in ionized form. Particles are existing as ions bearing positive and negative charges.
In oil and gas industry:
When crude oil get extracted from well, salt water and some other stuff needs to be removed before oil can be sued in the car
electrons in the outer shell have the lowest ionization energy. (not even gonna consider the quantum model which does funny things with d-sublevel). Highest ionization energy in descending order is:
Ar = 1520.6
Si = 786.5
Al = 577.44
Na 495.8
Answer:
(a) The slope of distance-time graph gives the speed of the objects.
As the slope of object (B) is the greatest among all, thus B has the largest speed and hence it is the fastest among all the objects.
(b) : As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.
(c) : On the y axis (i.e. distance line), 7 small represents 4 km
∴ 1 small line =
7
4
=0.57 km
Position of C at the instant B passes A is 8 km
(d) ; Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km
∴ Distance traveled by B =5.14−0=5.14 kmV
