I was reading about the term 'absolute zero' and I was wondering if at some point absolute zero and the most extreme temperature of heat meet to be one in the same....meaning that matter and energy cannot exist.

Is there a particular reason unimorphs only have just one thin piezo disc? Could two or more such piezo discs be used instead of just one to get greater sound output? Can a unimorph be made to produce low ultrasonic frequencies as well?

I am studying A Level Chemistry and my teacher asked a question.
What is ionisation energy?
I know it is, the energy needed to remove electrons.
Which element Nitrogen or Oxygen has higher first ionisation energy? Why?
It's Nitrogen right? But why?

Please also include what factors effect ionisation energy and please explain it too..

Thank You VERY MUCH!!! Wie Viele Danke...!!

A molecule in liquid is attracted by molecules from every direction (due to cohesive force)-- so there is no net force on it. But the surface molecules of liquid feel some net downward force coz their position (there is no liquid molecules upward to exert cohesive force).
When something feel a net force it is forced to move to direction of the force. But as we know the surface molecules normally does'nt exchange their position with lower surface molecules---
Now my question is what is the other force that balance the net downward force of surface molecules?
Thx.

same material turned in ash (by burning)?

I am talking about nutritanal and biological difference.

Why pHs of both end-products are different? And why we can use one very liberally (compost) and other (ash) sparingly?

I think the surface tension is due to the extra attraction among surface molecules.
Who exert the tension force? The surface molecules of course-- so it is nothing but a kind of molecular attraction.
