Question: What Is Difference Between NTP And STP?

What is NTP and why is it important?

Network Time Protocol (NTP) is a protocol that allows the synchronization of system clocks (from desktops to servers).

Having synchronized clocks is not only convenient but required for many distributed applications.

Therefore the firewall policy must allow the NTP service if the time comes from an external server..

How do I calculate STP?

It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”. R = 8.314472 J/mole x K.

What is r in pV nRT?

The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.

What is standard pressure in ATM?

1.01325 barThe standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). It is sometimes used as a reference or standard pressure. It is approximately equal to Earth’s atmospheric pressure at sea level.

What is the full form of NTP and STP?

NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated as NTP). Please note that these stated values of STP used by NIST have not been verified and require a source.

What is the volume of oxygen at STP?

Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

What is the value of STP?

Standard Temperature and Pressure (STP) is defined as 0 degrees Celsius and 1 atmosphere of pressure.

What is NTP and how it works?

The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. … NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC).

Is STP 25 or 0?

The standard state temperature is 25 degrees C (298 K). Note that temperature is not specified for standard state conditions, but most tables are compiled for this temperature. All gases are at 1 atm pressure. All liquids and gases are pure.

What is the volume at STP?

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L.

What is the volume of gas at STP and NTP?

22.4LIt is known that volume of a gas is equal to 22.4L at STP and NTP.

What do you mean by NTP?

Network Time ProtocolNTP stands for Network Time Protocol, and it is an Internet protocol used to synchronize the clocks of computers to some time reference. NTP is an Internet standard protocol originally developed by Professor David L. Mills at the University of Delaware.

What is the volume of 1 mole of gas at NTP?

22.4 LWe know that, 1 mole of gas occupies 22.4 L at NTP 1 mole of O2 gas occupies 22.4 L at NTP O2 contains 2 moles of oxygen atom.

What is STP formula?

VSTP = V * (273.15/T) * (P/760) This STP formula uses Kelvins, Torrs and Liters. Let’s add our data: VSTP = 5 * (273.15/350) * (850/760) VSTP = 4.364 L.

What is the volume of 1 mole of gas?

The molar volume at stp 1 mole of any gas occupies 22.4 dm3 at stp (standard temperature and pressure, taken as 0°C and 1 atmosphere pressure). You may also have used a value of 24.0 dm3 at room temperature and pressure (taken as about 20°C and 1 atmosphere).
