Is specific latent heat of ice is same for water or not?
The specific latent heat of ice and water is not the same. The specific latent heat of fusion for ice (the heat required to convert ice to water at 0°C) is approximately 334 kJ/kg, while the specific latent heat of vaporization for water (the heat required to convert water to vapor at 100°C) is significantly higher, around 2260 kJ/kg. Thus, the energy required for phase changes differs between ice and water.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
Does ice melt faster in water or alcohol?
Ice melts faster in water compared to alcohol because water has a higher specific heat capacity and thermal conductivity, allowing it to transfer heat more efficiently to the ice and accelerate the melting process. Alcohol has a lower specific heat capacity and thermal conductivity, so it is less effective at transferring heat to the ice.
If 20.6 grams of ice at -35c are heated and vaporized to all gas at 110c how much energy is required?
To calculate the energy required to heat and vaporize the ice, you need to consider the heat needed for each step: Heat the ice from -35°C to 0°C (specific heat of ice). Melt the ice at 0°C (heat of fusion). Heat the water at 0°C to 100°C (specific heat of water). Vaporize the water at 100°C (heat of vaporization). Heat the steam from 100°C to 110°C (specific heat of steam). Adding all these energies together will give you the total energy required.
How do you solve a problem finding the heat that is required to melt ice?
You would start by looking up the specific heat of fusion for ice. Then you multiply that by the amount of ice you're trying to melt (you may have to do some unit conversion to get your specific heat and ice mass in compatible units). That will give you the amount of heat required, and again you may need to do a unit conversion to get it in the units you want.
How much heat is necessary to change 565 g of ice at -13 and degC to water at 20 and degC?
To calculate the heat needed to change ice to water, we use the specific heat capacities and latent heat of fusion. First, calculate the heat needed to raise the temperature of 565 g of ice from -13°C to 0°C using specific heat capacity of ice. Then, calculate the heat needed to melt the ice at 0°C to water at 0°C using the latent heat of fusion for ice. Finally, calculate the heat needed to raise the temperature of water from 0°C to 20°C using the specific heat capacity of water. Add these three values together to find the total heat required.
How many grams of ice at -12.1 can be completely converted to liquid at 14.7 if the available heat for this process is 4390?
To calculate the heat required to convert ice to liquid at a temperature of 14.7°C, we first need to heat the ice from -12.1°C to 0°C, using the specific heat capacity of ice. Then we calculate the heat required to melt the ice at 0°C to water at 0°C, using the heat of fusion of ice. Finally, we calculate the heat required to heat the water from 0°C to 14.7°C, using the specific heat capacity of water. By performing these calculations, we can determine if the available heat of 4390 J is sufficient.
What do you need to know to calculate the heat needed to melt a block of ice at its melting point?
To calculate the heat needed to melt a block of ice at its melting point, you need to know the mass of the ice block, the specific heat capacity of ice, and the heat of fusion of ice (or latent heat of fusion). The formula to calculate this heat is Q = m * ΔHf, where Q is the heat energy, m is the mass, and ΔHf is the heat of fusion.
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.
How do you calculate the total heat required in kcal to take 70 grams of ice at -29.0 Celsius and convert it to steam at 106 Celsius?

How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
What is the amount of heat to change 10 lbs of ice at 20 degree F to steam 220 degree F?
To change 10 lbs of ice at 20°F to steam at 220°F, you would need to consider the heat required for each phase change: Heating the ice from 20°F to 32°F (melting point) - specific heat of ice Melting the ice into water at 32°F - heat of fusion of ice Heating the water from 32°F to 212°F (boiling point) - specific heat of water Vaporizing the water into steam at 212°F - heat of vaporization of water Heating the steam from 212°F to 220°F - specific heat of steam
