How many joules of energy are necessary to heat the steam from 100.0 AC to 114.0 AC if the specific heat of steam is 2.01 Jg AC?
To calculate the energy required to heat the steam, you need to use the formula: Q = mcΔT, where Q is the energy, m is the mass of the steam, c is the specific heat, and ΔT is the change in temperature. Given that the specific heat of steam is 2.01 J/g°C and the temperature change is 14.0°C, you would need to know the mass of the steam in order to calculate the total energy required.
How is a steam burn an example of latent heat?
A steam burn is an example of latent heat, because beside the heat released by the steam itself, a part of it condenses, turning into water, which in turn releases heat too.
How do you use thermodynamics steam tables?
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
How much joules would it take to heat 40 g of ice at -50 c to steam at 125 c?
To calculate the total energy required to heat 40 g of ice at -50°C to steam at 125°C, you would need to account for several steps: heating the ice to 0°C, melting the ice to water, heating the water to 100°C, converting the water to steam, and finally heating the steam to 125°C. This involves using the specific heat capacities and the latent heat of fusion and vaporization. The total energy is approximately 21,100 joules.
How much heat must be transferred for 20 g of liquid water at 100 C to become steam is it absorbed or released?
The heat required to convert 20 g of liquid water at 100°C to steam at 100°C is the heat of vaporization of water. This is 2260 J/g. Therefore, the total heat required is 20 g * 2260 J/g = 45200 J. This amount of heat is absorbed by the water as it changes phase from liquid to steam.
What is meant by wet and dry steam?
Dry steam is superheated , meaning more heat has been added resulting in no liquid phase present and the heat of vaporazation has been surpassed adding to the total enthahpy of the vapor. Wet steam is much like the steam rising from a pot of boiling water.
A kind of engine that uses water steam or heat?
A steam engine uses water, steam, and heat.
Steam turbine heat rate formula?
The efficiency of a steam turbine is just the ratio of power out to power in, but if you want to be able to calculate it from the basic mechanical design, this is a specialised topic. In the link below is a general description of steam turbines, in the references and additional reading list there are some references that may help you.
What form of energy are there in hot steam?
In hot steam, the main forms of energy present are thermal energy and heat energy. Thermal energy is the total kinetic energy of the particles within the steam, while heat energy is the transfer of thermal energy between objects due to a temperature difference.

How many btus are requiier to change five pounds of ice 20f to steam at 220f?
To change 5 pounds of ice at 20°F to steam at 220°F, you would first need to heat the ice to its melting point, then heat the water to its boiling point, and finally convert the water to steam. The total heat required can be calculated using the specific heat capacities of ice, water, and steam, as well as the heat of fusion and vaporization. The specific calculations would depend on the specific heat capacities and heat of fusion/vaporization values provided.

What enables a steam boat to run only on steam?
Nothing, a steam boat runs not on steam, but on a heat source GENERATING steam. this heat source is usually coal but could be wood or a fossil fuel.
