Answer:
Atom
Explanation:
The atom is the simplest unit of matter that has all the properties of an element. It is made up of 3 subatomic particles: protons, electrons and neutrons.
Knocking out the other choices, the cell is the basic unit of life. An electron is only part of an atom, which has its own properties, while a compound is a combination of two or more elements that are chemically bonded.
Answer:
D. Strong nuclear force, electrostatic force, weak nuclear force, gravitational force
An ideal diatomic gas at 80 k is slowly compressed adiabatically and reversibly to half its volume. The final temperature is 104.8k
<h3>Calculation of final temperature </h3>
The formula used for compression is:-
TV^(γ-1)=C
where;
T= temperature=80k
V=volume(given volume is half of its original volume i.e v/2)
γ=CP/CV= ( 7.R/2)/(5R/2)=7/5
C= constant
using the given values in the formula;
80 x V^[(7/5)-1]=T(final) (V/2)^[(7/5)-1]
80=T(final) x (V/V2)^(2/5)
80=T(final) x (1/2)^(2/5)
T(final)= 80 x (2)^2/5
T(final)= 80 x 1.31
final temperature =104.8k
