olga_2 [115]

Answer:velocity of molecules within a body

Explanation:

Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.

How many moles of N2 in 57.1 g of N2?
SpyIntel [72]

We are given –

  • Mass of \bf N_2 is 57.1 g and we are asked to find number of moles present in 57.1 g of \bf N_2

\qquad\pink{\bf\longrightarrow  { Molar \:mass \:of \: N_2:-}  }

\qquad\bf  \twoheadrightarrow 14\times 2

\qquad\bf \twoheadrightarrow   28

\qquad____________________

Now,Let's calculate the number of moles present in 57.1 g of \bf N_2

\qquad\purple{\bf\longrightarrow  { No \:of \:moles = \dfrac{Given \:mass}{Molar\: mass}}}

\qquad\bf   \twoheadrightarrow \dfrac{57.1}{28}

\qquad\bf  \twoheadrightarrow 2.04\: moles
