Why do we use STP in chemistry?
STP stands for standard temperature and pressure. Because gases occupy different volumes at different temperatures and pressures, it is necessary to define a set of conditions that can be considered standard.At STP:The temperature is 0°C or 273 KThe pressure is 1 atmosphere or 760 mmHg or 760 torrOne mole of any gas occupies 22.4 L of volume (molar volume)
What is the difference in pressure between a gas at 720mm and a gas at standard pressure?
Standard pressure is 760mm Hg, so the difference in pressure is 40mm Hg (760mm - 720mm).
What is the difference between cell potential and standard cell potential?
the standard cell potential is the cell potential at standard conditions (25C , 1 atm , and 1M ) but the cell potential is the cell potential of the cell under a real condition and we use nernst equation . i hope this is useful
What is the freezing point of water on the Kelvin scale at standard pressure?
100.... The size of a unit of heat energy in the Celsius and Kelvin temperature system is the same. Thus the difference between the boiling and freezing points of water at standard pressure is 100 units on either scale.
Why pressure is constant in Charles law?
In Charles's Law, pressure is assumed to be constant because the law specifically focuses on the relationship between volume and temperature of an ideal gas when pressure is held constant. This allows for a direct proportionality between volume and temperature, showing that as temperature increases, the volume of a gas will also increase if pressure is held constant.
What is the average distance between oxygen molecules at Standard Temperature and Pressure (STP)?
The average distance between oxygen molecules at Standard Temperature and Pressure (STP) is approximately 3.3 nanometers.
What is the difference between NTP and STP?
Yes, there is a little difference between NTP (Normal Temperature-Pressure) & STP (Standard Temperature-Pressure). There are detailed scientific and encyclopedic reasons behind it.
What is the difference between the standard volume and gross volume?
Gross volume is the volume at actual condition whereas standard volume is at standard Pressure/Temperature condition.
What is the comparison between heat and temperature?
porpotional
Which combination of temperature and pressure correctly describes standard temperature and pressure or STP?
The pressure of a has at STP is 1 bar.
Standard temperature and pressure are equal to?
In chemistry, standard conditions for temperature and pressure (informally abbreviated as STP, Standard Temperature Pressure) there are two (slightly different) standard sets of conditions for experimental measurements, to allow comparisons to be made between different sets of data.Two different standards:IUPAC's version of standard is a temperature of 0 °C(273.15 K, 32 °F) and an absolute pressure of 100kPa (14.504 psi, 0.986 atm)NIST's version is a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 101.325 kPa (14.696 psi, 1 atm).
Comparison between an unknown quantity and a standard?
A comparison between an unknown quantity and a standard is known formally as a measurement. In essence, by taking a measurement of a standard against an unknown quantity, you are creating your own system of measurement.
What is the difference between lpm and slpm?
"Lpm" stands for liters per minute, while "slpm" stands for standard liters per minute. Standard liters are measured at a specific set of conditions, typically at standard temperature and pressure (STP). The difference between lpm and slpm is that slpm takes into account the variations in gas density that can occur due to changes in temperature and pressure.
What does the pressure vs temperature graph reveal about the relationship between pressure and temperature in the system?
The pressure vs temperature graph shows that there is a direct relationship between pressure and temperature in the system. As temperature increases, pressure also increases, and vice versa. This relationship is known as the ideal gas law.
Where can I find a site that will show me the ins and outs for a good comparison of the light vs. standard laptop?
www.geek.com is the website that provides a good comparison of a light and standard laptops. This website provides all ins and outs of comparison between light and a standard laptop in a detailed manner.
What does the temperature degree mean?
Temperature degrees are a measurement of the average kinetic energy of particles in a substance or object. It indicates how hot or cold something is relative to a standard reference point. The degree scale is used to quantify temperature and enable comparison between different systems.
What are the nonmetal elements at room temperature?
The only metal element to exist in a non-solid state at room temperature is Mercury, which is a liquid between -38.83 °C and 356.73 °C at standard pressure.
