    Temperature is only a measure of the average kinetic energy, however you could say that the work done in bringing the molecules fromliquid to gas is much greater than the work done in separating molecules from solid to liquid state.

    Have you read this booklet? It's got everything in it. The most important topics? I don't think there is one. I've done all the past papers and Ive seen everything in at least one paper. From opamps, mbiles, remote sensing (xrays, mri, etc). If you haven't read the booklet, take a look at it...

    As you heat a solid turning it into a liquid, you increase the kinetic energy of its molecules, moving them further apart until the forces of attraction are reduced to allow it to flow freely. Keep in mind the forces of attraction still exists. Now as you heat a liquid, turning it into a gas...

    I believe this is the right answer.. x-rays for medical diagnostic procedures or for research purposes are produced in a standard way: by accelerating electrons with a high voltage and allowing them to collide with a metal target. X-rays are produced when the electrons are suddenly decelerated...

    physics P4

    As you've answered one question, I have one similar for you! I need an A* in physics a level, and I got an 86% (UMS) grade. What grades more or less (cause we all know it depends on the thresholds) do i need in the A2 papers?

    A2 Physics | Post your doubts here

    Can anyone please help me with this? I need an A* in Physics A2, however my result at AS level was 86 in UMS. What grade do I need (more or less, cause its impossible to know specifically) in order to overcome the AS result and obtain one on the top 10%?
