WebChemistry is the study of matter and the changes it undergoes. Here you can browse chemistry videos, articles, and exercises by topic. We keep the library up-to-date, so you may find new or improved material here over time. ... Ideal gas equation: Gases and kinetic molecular theory Kinetic molecular theory: Gases and kinetic molecular theory ... WebConclusions. Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work following the equation: work = − P Δ V. \text {work} = -\text P\Delta \text V work = −PΔV.

WebTemperature difference T = 20 o C, Heat lost Δ Q = 300 J. the Heat capacity formula is given by. Q = mc ΔT. c= 300 / 20. c= 15 J/oC. Example 2. Determine the heat capacity of 3000 J of heat is used to heat the iron rod of mass 10 Kg from 20oC to 40oC. WebThe answer is False. If you solve the Ideal Gas equation for n (the number of particles expressed as moles) you get: n = PV/RT. Thus, at STP, the same volume of all gases have the same number of molecules (provided the conditions are suitable for the Ideal Gas Law to apply). A more dense gas has more MASSIVE molecules, but the same number of ...
