Words: 525 (3 pages)

Another postulate of the kinetic molecular theory is that gas particles are always in motion, like the other states of matter. But they are different in that they undergo random translational movement. In solids, the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate, with some translational motion. Gas particles move…

Don't hesitate to contact us. We are ready to help you 24/7

What can physical chemistry be used for?
physical chemistry, branch of chemistry concerned with interactions and transformations of materials. Unlike other branches, it deals with the principles of physics underlying all chemical interactions (e.g., gas laws), seeking to measure, correlate, and explain the quantitative aspects of reactions.
What is physical chemistry and its importance?
Physical chemistry is essential to understanding the other branches of chemistry. It provides a basis for understanding the thermodynamic influences (principally, the entropy changes accompanying reactions) that drive chemical reactions forward.
What is physical chemistry in your own words?
physical chemistry. noun. the branch of chemistry concerned with the way in which the physical properties of substances depend on and influence their chemical structure, properties, and reactions.
What is the importance of physical chemistry in our daily life?
Physical chemistry is essential to understanding the other branches of chemistry. It provides a basis for understanding the thermodynamic influences (principally, the entropy changes accompanying reactions) that drive chemical reactions forward.
