How much energy is required to change a 40 g ice cube from ice at 10C to steam at 1100C?
Trick or Treat!
Early chemical analysis used melting & boiling points (temperatures) to establish the purity of samples. As temperature rises in a pure substance, the change in temperature will stop rising in the substance until the phase change is complete (solid [ice]=>liquid [water] & liquid [water]=>vapor [steam].
Therefore the [energy] heat would be the sum of raising the mass of ice to it's melting point plus the heat necessary to make the change of state plus the heat to raise the temperature of water to it's boiling point plus [the trick] the heat required to raise the temperature of steam to 1100 degree C. but gases [vapor] temperature involves changes in pressure (PV=nRT) so unless it is in a sealed container, the water would boil away never reaching the temperature.
If in a sealed container there would be the dependent variable of container volume,

Is conversion of steam to water an exothermic reaction?
Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
What happens when energy is added to water at 100 C?
When energy is added to water at 100°C, the water will undergo a phase change from liquid to vapor (steam) without a change in temperature. This process is called vaporization or boiling. Once all the liquid water has converted to steam, further addition of energy will increase the temperature of the steam.
What is the steam energy particle called?
While some forms of energy can be considered as either particle or wave, steam is not one of those. The energy of steam comes from it expansion. There is no steam energy particle.
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.
Steam is sometimes used to melt ice Is this change physical or chemical?
The use of steam to melt ice is a physical change. The ice is still the same substance (water), but it changes from a solid to a liquid form due to the gain of heat energy from the steam. No new substances are formed during this process.
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 many joules of energy are necessary to heat the steam from 100.0 degree c to 114.0 degree c?
To calculate the energy required to heat a substance, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. You will need to know the specific heat capacity of steam to determine the energy required to heat it.
What kind of energy does a steam engine change to?
Heat And Kinetic Energy
How much energy is required to change 34.71 g of liquid water to steam?
The answer will depend on the temperature of the liquid water and the pressure.
Why does it take 80 calories to convert 1 gram of water to 1 gram of steam?
Water molecules attract each other; energy is required to overcome that attraction. In other words, the change of phase implies a change in potential energy.
How many btus are required to change 10 pounds of steam at 212 degrees to 240 degrees?
To calculate the heat energy required to change the temperature of a substance, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Given that steam has a specific heat capacity of approximately 0.5 btu/lb°F, you can calculate the required heat energy by plugging in the values: Q = 10 lb * 0.5 btu/lb°F * (240°F - 212°F).
How many BTU's to change 22 degree ice to 222 degree steam?
To change 1 gram of ice at 22 degrees Fahrenheit to steam at 212 degrees Fahrenheit, you would need approximately 1064.73 BTUs. This calculation takes into account the energy required to melt the ice, heat the water, and then boil it to steam.
How much heat must be removed from steam to change it to a liquid?
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
How much energy is required to change 80g of ice at -30 degrees celsius to steam at 140 degrees Celsius?
To calculate the total energy required, we need to consider the energy required for each phase change using the specific heat capacities and latent heat of fusion/vaporization. The energy required can be broken down into: heating the ice from -30°C to 0°C, melting the ice at 0°C, heating the resulting water from 0°C to 100°C, boiling the water at 100°C, and heating the steam from 100°C to 140°C. The total energy can be calculated using these components.
What specific heat is the energy used to evaporate water or melt snow?
The specific heat of water is the amount of energy required to raise the temperature of water by 1 degree Celsius. The heat of vaporization is the energy required to change water from a liquid to a gas (steam) at its boiling point. The heat of fusion is the energy required to change water from a solid to a liquid (melt snow) at its melting point.
What has more energy steam or water?
Steam has more energy than water at the same temperature because it is a gas, while water is a liquid. The energy difference is primarily due to the latent heat of vaporization, which is the energy required to convert water into steam. This energy allows steam to carry more heat energy and perform work, making it more energetic than liquid water.
How does a steam engine change chemical energy to heat energy?
A steam engine uses a hydrocarbon based fuel source. The combustion of the fuel releases the chemical energy in the bonds in the form of thermal energy.
