Q=0 in an adiobatic system because it's an insulated system (let's imagine an ideal system) where there's no temperature change. If change in internal energy is always equal to …

Pros: zero carbon emissions, large fuel supplies available, can produce large amounts of electricity. Cons: nuclear safety of operating reactors, huge capital costs and disposal of …

The periodic table of elements is an amazing classification tool. There are many things that we chemists do which only require a quick glance at the table to obtain the answer we require. …

270J From definition, Kinetic energy E_k=1/2mv^2. So in this case, E_k=1/2xx60xx3^2 =270J

The electron volt (eV) is a unit of energy equal to approximately 1.6×10−19 joule (J). By definition, it is the amount of energy gained (or lost) by the charge of a single electron moved across an …

Photons by definition have zero mass. Photons are the quanta of light. They always travel at the speed of light - though the speed of light is fastest in a vacuum and slower in media such as …

Even attempting to 'Prove' laws of thermodynamics on an experimental and quantifiable level is incredibly expensive and challenging. The first law of thermodynamics states that in an …

When a gas undergoes an expansion without energy being supplied from outside, the energy required for the expansion to take place comes at the expense of the internal energy of the …

Mitochondria are site of oxidative phosphorylation, i.e. production of ATPs utilizing energy liberated in exothermic chemical reactions. Mitochondria are cell organelle concerned with …

A reaction's change in Gibbs free energy, ΔG, tells you whether or not that reaction is spontaneous or not at the specific temperature at which it takes place. A chemical reaction's …
