How do you calculate joule kelvin inversion temperature of hydrogen?
use the T=2a/(bk) equation shown in the first link, plugging in a and b values found in the second link. proofs are shown in the joule-thomson expansion wikipedia page as well as the van der waals equation of state page.
Latent heat of vaporisation decreases as pressure increases and becomes zoro at critical pressure i read . why it so?
At critical pressure, the distinction between liquid and gas phases disappears as the substance exists as a supercritical fluid. In this state, the latent heat of vaporization becomes zero because there is no longer a clear boundary between the liquid and gas phases for the substance to transition between. The behavior of the substance at critical pressure is unique and results in the disappearance of the latent heat of vaporization.
What is true about the temperature of melting point and boiling point?
Under ordinary conditions they are the same 'point'. For example, water just freezes and it just melts at zero degrees centigrade. The difference between the two states is not temperature, but the heat of fusion. When the heat of fusion is removed from water at zero degrees, it will freeze. When the heat of fusion is added to ice at zero degrees, it will melt.
State the relationship between heat and temperature?
Temperature is what measures heat. If you're measuring the temperature in Celsius, then you're measuring the amount of heat above the freezing point of water. In Kelvin, it's the amount of heat above absolute zero. In Fahrenheit it measures the amount of heat above the freezing temperature of a specific compound.
How much electricity does it take to melt 1 cubic meter of ice?
This is too complicated to give a complete answer, but how about this to start with. When ice melts it changes it's state from solid to a liquid . Water can have a temperature of zero centigrade and ice can have a temperature of zero centigrade . To change it's state from ice to water, or water to ice there is a considerable amount of 'heat' involved . Heat is measured in a unit called the Calorie . To change ice back to water it must absorb heat energy. It requires about 80 Calories of heat per gram of ice, just to melt it all. This heat energy is called the 'Latent heat of Fusion'. There is no change in temperature whatever, when the zero degrees Ice changes to zero degree water. There is simply a lot of 'heat' exchanged. I will let you calculate how many grams of ice in a cubic Metre, but it is an enormous quantity of grams . When you get the answer, multiply it by 80 and that is the number of calories of heat energy needed to do the job. Now you will need to calculate the number of Watts of electrical energy needed to perform the task of supplying all that heat. There is a direct relationship between watts of electrical energy, and calories of heat energy. Be very aware that temperature and heat are totally different things, having totally different units.

What temperature is no heat found?
Zero Kelvin by definition
What is the temperature when there is no heat energy?
When there is no heat energy, the temperature would theoretically be absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, all molecular movement ceases, and no heat energy is present. This temperature is purely theoretical and cannot be reached in practice.

At critical pressure, the distinction between liquid and gas phases disappears as the substance exists as a supercritical fluid. In this state, the latent heat of vaporization becomes zero because there is no longer a clear boundary between the liquid and gas phases for the substance to transition between. The behavior of the substance at critical pressure is unique and results in the disappearance of the latent heat of vaporization.
Temperature when there is absolutely no heat energy at all?
That's the definition of "Absolute Zero".
What is the defiinition of temeperature?
Temperature is the amount of heat energy compared to absolute zero.
The critical pressure at which the latent heat of vaporization for water is zero is?
Its the temp AND pressure at which there is no difference between the liquid water and the vapor (steam) for water that is - around 647 K (374 °C; 705 °F) and 22.064 MPa (3200 PSIA or 218 atm)
How does the Kelvin scale link to heat?
The Kelvin scale is an absolute temperature scale where zero represents absolute zero, the theoretical absence of all heat energy. As temperature increases on the Kelvin scale, so does the average kinetic energy of particles, indicating a rise in heat energy. This means that a higher Kelvin temperature corresponds to more heat energy present in a substance.
What is the temperature with absolutely no heat source?
The temperature in a complete vacuum, with no heat source, would be absolute zero, which is equivalent to -273.15 degrees Celsius or 0 Kelvin. At this temperature, all molecular motion ceases, and no heat energy is present.
The impossibility of reaching a temperature of absolute zero is incorporated in?
The Third Law of Thermodynamics."Absolute zero (0 K) is the lower limit of temperature. The temperature of absolute zero cannot be attained physically because to do so would require virtually all the heat to be taken from an object. Therefore, it is impossible to attain a temperature of absolute zero."
Is absolute zero a measure of temperature?
Absolute zero is the temperature at which entropy reaches its minimum value. So yes, it is a measure of temperature. No temperature is lower than absolute zero. All motion stops at absolute zero as there is no energy left. Remember, energy is measured in heat so if there is no heat then there is nothing to allow any type of motion or activity etc.
Why isn't it possible to have a measurement of heat that is below zero?
Temperature is a measure of the average kinetic energy of particles in a system. It is not possible for this average energy to be "negative" as it would imply a state of less than zero energy, which is not physically meaningful. This is why temperature measurements cannot go below absolute zero, the point at which particles theoretically have zero kinetic energy.
