WebJan 26, 2016 · A monatomic gas is defined as a gas composed of single atoms. Ex - He gas or Ne gas where all the atoms are single or monoatomic. Diatomic on the other hand has two atoms per molecule. Ex- H2 or N2 etc. Internal energy of monatomic gas is = (3/2)RT and for a diatomic gas is (5/2)RT. Top. WebApr 4, 2024 · Helium is considered monoatomic because it has 1 atom in its molecule, but hydrogen is considered diatomic because it has 2 atoms of hydrogen in its molecule. Is …
WebSince the air is dominated by diatomic gases (with nitrogen and oxygen contributing about 99%), its molar internal energy is close to c v T = (5/2) R T, determined by the 5 degrees of freedom exhibited by diatomic gases. [citation needed] [circular reference] See the graph at right. For 140 K < T < 380 K, c v differs from (5/2) R d by less than 1%. WebDiatomic molecules consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Many compounds are diatomic, such as …
