A/ pressure and collision frequency increase.
think of it this way. there's less room in total when u decrease volume, so particles will hit more often because they travel less
False an atom can not have an electric charge.
Answer:Heat is kinetic energy the higher the temperature of a substance, the faster and farther its molecules move. For example, as heat transfers into the ice, the ice molecules move faster and eventually the ice melts When those molecules slow down, their kinetic energy decreases
Hope this helps! :)
Answer:
C: Solutions W and Y have greater solubility than solutions X and Z.
Explanation:
Temperature and pressure affect the solubility of a solution as follows:
- the higher the pressure, the greater the solubility (because more pressure means more collisions between the molecules, so this improves the solubility)
- the higher the temperature, the greater the solubility (because higher temperature means higher kinetic energy of the molecules, so more collisions, and so this improves the solubility)
Therefore, considering these two factors, the solutions with greater solubility must be W (which has high pressure) and Y (which has high temperature).
<span>The sprinter is advised to reduce his speed slowly after
completing the race because of the power that is needed when the stoppage is
down in a faster manner could be very great. This would translate to the great
usage in gasoline. Also, the inertia of the vehicle is quiet high so it is hard
to stop it very suddenly. </span>
