Chemistry is the branch of science which studies matter—its composition, prop-erties, and changes. Scientists attempt to discover and describe matter, then deter-mine why these kinds of matter have particular characteristics and why changes in this matter occur.

14 Νοε 2022 · Explain the meaning and use of unit dimensions; state the dimensions of volume. State the quantities that are needed to define a temperature scale, and show how these apply to the Celsius, Kelvin, and Fahrenheit temperature scales. Explain how a Torricellian barometer works.
Effect of temperature on reaction rate: Increasing the temperature means the particles will have more kinetic energy and so will move faster. If the molecules are moving faster they will collide more often and, since they’ve gained kinetic energy, a larger proportion of the particles will have at least the activation energy.
This book introduces chemistry to beginners. It does this “progressively”, that is, the presentation moves logically from experimental observations to theory.
