What temperature on the Celsius scale is equivalent to 373K?
373K = 99.85 degrees Celsius. [°C] = [K] − 273.15
How many degrees Celsius are in 373 kelvin?
The answer is 99.85 C (approx.). The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from K to C, subtract 273.15 from K.
What happens to the internal energy of an ideal gas when it is heated from 0 Celsius to 4 Celsius?
It depends on the circumstances, if the gas is in a flexible container and the pressure exerted on the gas is constant throughout the heating the it's volume will increase. This is governed by Charles law V1/T1=V2/T2 (here the temperatures must be expressed in Kelvin O0C = 273 K and 1000C = 373K) On the other hand, if the gas is in a container that can't expand, such as a steel cylinder, then it's volume will remain constant and it's pressure will increase, this is governed by Amonton's Law which is very similar to Charles' Law but deals with the relationship of pressure and temperature P1/T1=P2/T2 again the temperatures must be expressed in Kelvin for the calculations to be accurate.
Which contain more heat 1 kg of steam at 373k or 1 kg of water at 373k?
i think 1 kg steam
Which would mostlikely be the temperature of boiling water?
373K
What temperature does water boil at in Kelvin?
It boils at 373 degrees kelvin. Kelvin is just Celsius plus 273. Water boils at 100C, 100+273=373, so 373K.
At what tempetier does water boil?
100°C (Celsius), 212°F(Fahrenheit), or 373K(Kelvin)
What temperature on the Celsius scale is equivalent to 373K?
373K = 99.85 degrees Celsius. [°C] = [K] − 273.15
What temperature does water produce steam?
It depends on the pressure of the system that the water is in. In atmospheric pressure (ie at sea level and in the open) water turns into steam at 100 degrees Celsius. At higher pressures this temperature decreases.
What are the three temperature systems?
There's really only one scientific measurement for temperature, and that's the Kelvin scale. The commonly used systems for weather are Celsius and Fahrenheit. Water freezes at 273K, 0C, and 32F. Water boils at 373K, 100C, and 212F.
How can we use the boiling point of a liquid to decide if the liquid is pure?
on adding non-voatile substance there in an increase in bp of substance...for instance water with a non-volatile solute will h boiling point greater than 373K
Is kelvin used to express forces such as weight in SI?
no kelvin is used to measure temperature it ranges from 273K to 373K
How does you test purity of substance?
Purity is measured by chemical analysis. The analysis should determine both what the substance is, and what impurities it contains. There are several analytical techniques available, depending on what you want to know. For organic compounds, the most common are infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance spectroscopy. Other methods include titration and combustion analysis. A pure substance always has the same colour, taste or texture at a given temperature and pressure. Also it has a fixed melting point or boiling point at constant pressure. For example, pure water boils at 373K at 1 atmospheric pressure. But water containing some invisible dissolved substance boils at a temperature above 373K.
1 gm of water occupies how much volume in cm3 at 373K?
The density of water changes with temperature. However, at standard atmospheric pressure, when water reaches 373 K (which is 100 °C or the boiling point of water), it starts to turn into steam. The density of water just before boiling (still in the liquid state) is less than its density at room temperature (about 1 g/cm³ at 4 °C). However, for most practical purposes, especially close to the boiling point, we can still approximate the density of water to be close to 1 g/cm³. This is because while the density decreases with temperature, the change is not extremely large until the water actually begins to convert into steam. Therefore, at temperatures close to but not above the boiling point, 1 gram of water would occupy a volume close to 1 cubic centimeter (cm³), given that the density is approximately 1 g/cm³. Note that this is an approximation, as the exact volume could be slightly more due to the decrease in density with increasing temperature. But without specific density values at 373 K for liquid water, this standard approximation is commonly used.
