the ideal gas law equation is as follows
PV = nRT
where P - pressure
V - volume
n - number of moles
R - universal gas constant
T - temperature
so if the pressure, volume and temperature are already known
we are left with n and R
since R is the universal gas constant that has a known fixed value then R too is known
so we are left with 'n'
once we know temperature volume and pressure
we can find the number of moles of gas present using the ideal gas law equation
A.) the molar amount of gas
Hope it helps!
Answer:
As we all are aware that life on Earth is existed due to several environmental changes and there are several scientific factors of sustainability that support the survival and evolution of life on Earth.
Scientific factors of sustainability include solar energy, chemical cycle, and biodiversity that supported life on Earth.solar energy helps all organism and especially producers to gain energy and store the energy which further used in chemical cycles of transferring energy to other trophic levels.
Chemical cycle also involves the interaction of biotic and abiotic envrionment with each other that leads to environmental changes as well as organisms adapt themselves accordingly.
Biodiversity maintains the balance in the ecosystem and prevent dominancy of one organism otherwise it can lead to scarcity and organism would not be able to survive. Variation in biodiversity due to random mating in the same species leads to evolution and produces new species of organisms.
Hence, scientific factors of sustainability play major role in survival and evolution of life on the Earth.

(b)A gas exerts pressure on the
walls of the container
(c) A wooden table should be
called a solid
(d) We can easily move our hand
in air but to do the same
through a solid block of wood we need a karate
expert
we need a karate expert.
Answer:
A.A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. ... These collisions of the gas particles with the container walls exert pressure on the walls of the container.
B A gas exerts pressure on the walls of the container due to imapact of its gas molecules with hight velocity .
C.A wooden table should be called a solid. Reason: It has a definite shape and volume. It is very rigid and cannot be compressed, i.e., it has a solid characteristic.
D.We can easily move our hand in air but to do the same through a solid block of wood we need a karate expert. It is because the molecules of air has less force of attraction between them and a very small external force can separate them and pass through it.
