Which postulate of the kinetic-molecular theory best describes the event in the diagram?
Most of the volume of a gas is empty space.
All collisions between particles are perfectly elastic.
There is no force of attraction or repulsion between gas particles.
The /erage kinetic energy of particles denandir onu

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

the answer for sodium is 0.186

the answer for rubidium is 0.251

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
