Open vs. closed vs. isolated systems Figure 1: Different types of systems in relation to the surrounding environment. Credit: Alkh.Alwa – diagram, CC BY-SA 4.0. Another classification of a system describes systems as open, closed, or isolated. Open systems exchange energy and matter with th...
What is heat? Learn about the effects of heat and the properties of heat on objects. Understand the modes by which heat transfer takes place by...
Chemical equilibrium exists when a reversible chemical reaction occurs within a closed system, such as a sealed flask, and the rate of the reaction in the forward direction equals the rate of the reaction in the reverse direction. For example: N 2 + 3H 2 ⇄ 2NH 3 . ...
The first law of thermodynamics states that the amount of energy in the universe is a constant; it only moves from the system to the surroundings (or vice versa) or changes forms. In thermodynamics, when the movement of energy is studied, it is done with the help of an abstract model. ...
In living systems, thelipidbased membrane creates compartments which allow the transport of a selective concentration of water-soluble substances. The ions, small molecules, proteins, and other solutes have different concentration across the membranes. Hydrophilic, polar or charged molecules cannot cross ...
Electrochemical cells that produce electric energy from chemical energy are the basis of primary and secondary (storage) batteries and fuel cells. Other electrical phenomena of interest in chemical systems include the behavior of ionic solutions and the conduction of current through these solutions, the...
examples of heterogeneous equilibrium equilibrium constant in heterogeneous system equilibrium in physical change faqs equilibrium in heterogeneous system in a chemical reaction, the reacting species combine with each other to form products. if such a reaction is carried out in a closed container, in ...
activities. For example, when a tightly closed glass jar with a metal lid is held over a flame, the lid thermally expands more than the body, making it easier to undo the jar. Similarly, the thermal expansion of mercury is used in mercury thermometers to measure the surrounding temperature....
