Answer:
15.24 J is the change in internal energy for this process.
Explanation:
According to the first law of thermodynamics:-
Where,
U is the internal energy
q is the heat
w is the work done
From the question,
q = + 75 J
(+ sign as the heat is being absorbed)
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 2.00 - 1.40 L = 0.60 L
P = 1.02 atm
Also, 1 atmL = 101.3 J
So,
(work is done by the system)
So,
<u>15.24 J is the change in internal energy for this process.</u>
Explanation:
Our environment is very important to us because it is where we live and share resources with other species. ... Environmental science enlightens us on how to conserve our environment in the face of increasing human population growth and anthropogenic activities that degrade natural resources and ecosystems.
I’m so sorry I actually really don’t know The answer
Color
Streak. (What color is the line it leaves behind?)
Hardness(how hard or soft the mineral is)
Lust(the way the mineral reflects light)
Florescence. (Does it glow under UV light?)
Magnetism. (Is it magnetic?)
Cleavage or fracture. Does it break evenly?(Cleavage) Or does it shatter into several pieces?(Fracture)
Crystalline structure(What is its shape?)
Taste. What does it taste like?(Do not use this)
Odor. (What does it smell like?)
Transparency. (Can you see through it?)
