Explain whether smoke filling up a room is diffusion or not.

Answers

yes it is diffusion ..
explanation :
 diffusion is the movement of particles from high concentration to low concentration .. 
as the smoke rises at one corner of the room soon it spreads all over the room which is simply diffusion ..
Yes this is diffusion because diffusion is the movement of particles from high concentration to low concentration, so when smoke go up in one corner then the smoke goes all over the room which is diffusion.

What is the relationship between the kinetic energy of molecules in an object and the object's temperature?as the temperature increases, the kinetic energy of the molecules increases

the kinetic energy always increases whether the temperature increases or decreases

the total kinetic energy of the molecules is not affected by a change in temperature

as the kinetic energy of the molecules decreases, the temperature increases

Answers

Answer: as the temperature increases, the kinetic energy of the molecules increases

Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.

Kinetic energy of the particles is directly proportional to the temperature of the gas.

K.E=(3RT)/(2)

where T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.



The production of the energy by the moving particle is called kinetic energy. The kinetic energydepends on the following:-

  • Mass
  • Velocity

The kinetic energy of every state is different i.e the kinetic energy of the solid, liquid, and gas are different. The kinetic energy of the particles is directly proportional to the temperature of the gas.

T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.

Hence, the correct option is A
