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.
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.
The literature value for the specific heat of chromium is approximately 0.449 J/g°C.
The specific heat of uranium is approximately 0.116 joules/gram degree Celsius.
The type of liquid affects how fast an ice cube will melt due to its thermal conductivity and specific heat capacity. Some liquids, like water, have high thermal conductivity and specific heat capacity, leading to faster melting of the ice cube. Other liquids, like oil, have lower thermal conductivity and specific heat capacity, resulting in slower melting of the ice cube.
The specific heat value for water is 4.18 J/goC.
No, it is not possible for the specific heat of a substance to have a negative value.
it doesnt, water has the same specific heat no matter what temperature it is at...about 4.18. Specific heat is a characteristic value of materials to resist changes in temperature (heat flow). Please rephrase the question if this is not the answer you are after

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.
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.
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.

Specific heat of water is 1 calory per gram .
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.
The amount of heat needed to melt 2 kg of ice is 334,000 Joules. This value is known as the heat of fusion of ice, which is 334 kJ/kg.
The literature value for the specific heat of chromium is approximately 0.449 J/g°C.
