Transport Layer Security ( TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to provide security ...

From the ideal gas law PV = nRTwe get: 1. R = P V n T {\displaystyle R={\frac {PV}{nT}}} where P is pressure, V is volume, n is number of moles of a given substance, and T is temperature. As pressure is defined as force per area of measurement, the gas equation can also be written as: 1. R = f o r c e a r e a × v o l u m e a m o u n t × t e m p e r...
The Boltzmann constant kB (alternatively k) may be used in place of the molar gas constant by working in pure particle count, N, rather than amount of substance, n, since: 1. R = N A k B , {\displaystyle R=N_{\rm {A}}k_{\rm {B}},\,} where NA is the Avogadro constant.For example, the ideal gas lawin terms of the Boltzmann constant is: 1. P V = N k B...
As of 2006, the most precise measurement of R had been obtained by measuring the speed of sound ca(P, T) in argon at the temperature T of the triple point of water at different pressures P, and extrapolating to the zero-pressure limit ca(0, T). The value of Ris then obtained from the relation: 1. c a ( 0 , T ) = γ 0 R T A r ( A r ) M u , {\displays...
The specific gas constant of a gas or a mixture of gases (Rspecific) is given by the molar gas constant divided by the molar mass (M) of the gas or mixture: 1. R s p e c i f i c = R M {\displaystyle R_{\rm {specific}}={\frac {R}{M}}} Just as the molar gas constant can be related to the Boltzmann constant, so can the specific gas constant by dividin...
The U.S. Standard Atmosphere, 1976 (USSA1976) defines the gas constant R∗as: 1. R∗ = 8.31432×103 N⋅m⋅kmol−1⋅K−1 = 8.31432 J⋅K−1⋅mol−1. Note the use of kilomoles, with the resulting factor of 1000 in the constant. The USSA1976 acknowledges that this value is not consistent with the cited values for the Avogadro constant and the Boltzmann constant. T...
Ideal gas calculator Archived 2012-07-15 at the Wayback Machine– Ideal gas calculator provides the correct information for the moles of gas involved.Greenhouse gases ( GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. [1] .
The Bhopal disaster or Bhopal gas tragedy was a chemical accident on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.[1] The technology eliminates the need for individually configuring network ...
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations.
