Which of the sentences below is true about the molecules of water in pictures 1 and 2Select onea The average kinetic energy of water molecules in picture 1 is t class=

Respuesta :

When Temperature increases the velocity of the molecules increases, since the kinetic energy is given by:

[tex]\begin{gathered} K=\frac{1}{2}mv^2 \\ Where: \\ m=mass \\ v=velocity \end{gathered}[/tex]

The velocity is directly proportional to the kinetic energy, therefore, the kinetic energy increases too.

Answer:

b. The average kinetic energy of water molecules in picture 1 is greater than those in picture 2.
