What are Megapascals, Entropy and Enthalpy?

Sep 13, 2017

Well, $\text{megapascals}$ are a unit of pressure....

Explanation:

And $\text{1 megapascal}$ $=$ $1 \times {10}^{6} \cdot P a \equiv 1 \times {10}^{6} \cdot k g \cdot {m}^{-} 1 \cdot {s}^{-} 2$.

And entropy is commonly defined as the statistical probability of disorder.....and is a measure of the randomness of a chemical substance.

And enthalpy is defined as the latent heat of a system.

Both $\text{entropy}$ and $\text{enthalpy}$ are commonly used terms in thermodynamics, and both are extensive parameters, that can be quantitatively measured. Please note that this answer is NO SUBSTITUTE for looking up the relevant chapters in your text, AND also doing problems where entropy and enthalpies are calculated.
