Answer:
Gases, liquids and solids are all made up of microscopic particles.
Note that:
Particles in a:
gas are well separated with no regular arrangement.
liquid are close together with no regular arrangement.
solid are tightly packed, usually in a regular pattern.
Particles in a:
gas vibrate and move freely at high speeds.
liquid vibrate, move about, and slide past each other.
solid vibrate (jiggle) but generally do not move from place to place.
Liquids and solids are often referred to as condensed phases because the particles are very close together.

btw... IS THAT SPANISH?!
I HAD TO DO THIS ON ENGLISH LOLOLO
Answer:
ΔU= 1.3922 KJ
Explanation:
Given that
Q= 2 KJ
Note- 1 .Heat added to the system taken as positive and heat leaving from the system is taken negative.
2. Work done on the system taken as negative and work done by the system taken as positive.
P =2 atm
V₁= 2 L
V₂=5 L
Work done by the gas W
W= P ( V₂- V₁)
W= 2 ( 5 - 2)
W= 6 atm.L
1 L·atm = 0.1013 kJ
W= 0.6078 KJ
From first law of thermodynamics
Q= W + ΔU
ΔU=Change in internal energy
2 = 0.6078 + ΔU
ΔU= 1.3922 KJ
-- The greatest common factor of 2525 and 3535 is 5.
-- So the greatest possible number of teams is 5.
-- Each of the five teams will have 505 girls and 707 boys.
-- Rafaela is a superwoman ! She's handling more kids in that class than there were in my whole high school !
She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.
But come on ! She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only' 1,212 students on it !
And these are all in one class ! If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !
Or maybe not. I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.
And possibly several OTHER schools in town too.
