Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
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 much heat is required to melt 68.5 g of ice at its melting point?
The heat required to melt ice at its melting point is known as the heat of fusion, which is 334 J/g. Therefore, the heat needed to melt 68.5 g of ice is 68.5 g x 334 J/g = 22,939 J.
How many photons at 660 nm must be absorbed to melt 5.0 x 10 x10 g of ice?
To calculate the number of photons needed to melt the ice, you would need to determine the energy required to melt the ice and then convert that energy into photons at 660 nm. This involves calculating the energy required to melt the ice using the heat of fusion of ice and then dividing that by the energy of a photon at 660 nm.
How many joules of heat are required to melt 40 kg of ice at 0 dg C?
In order to answer this question, you need the enthalpy of fusion of ice, which is 333.55 J/g (Joules/gram). The enthalpy of fusion is the amount of heat that must be absorbed or lost in order to change physical state. The number of Joules required to melt the ice = enthalpy of fusion of ice x mass of ice. 1 kg = 1000g 40kg x (1000g/1kg) = 40,000g Joules needed to melt the ice = 333.55 J/g x 40000 g = 13342000 J or 1.3342 x 107 J
How is the amount of heat needed to melt ice related to the amount of heat needed to freeze the same amount of water?
The two amounts are the same but have the opposite sign (positive vs negative).
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.

How many joules of energy are needed to melt 54-grams of ice at its melting point?
The specific latent heat/ latent heat of fusion of ice is 333.55 J/gtherefore by using the equation E=mLE = 54 * 333.55= 18011.7 JTherefore the energy needed to melt 54 grams of ice at its melting point which is keeping it at 0 degrees Celsius is 18011.7 Joules.
How much heat is required to melt 68.5 g of ice at its melting point?
The heat required to melt ice at its melting point is known as the heat of fusion, which is 334 J/g. Therefore, the heat needed to melt 68.5 g of ice is 68.5 g x 334 J/g = 22,939 J.
When you melt ice what heat is it called?
When melting ice, you are moving from a solid to a liquid. Any state change from a solid to a liquid is called the heat of fusion. In other words, whenever melting takes place, the amount of energy needed is referred to as the heat of fusion.
What is heat of fusion of water to melt ice cube?
The heat of fusion of water, which is the amount of heat energy required to melt one gram of ice at its melting point, is approximately 334 joules per gram. This means that to melt an ice cube, the ice must absorb 334 joules of heat energy per gram to transition from a solid to a liquid state.
What temperature does ice melt fastest?
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
How much energy is needed to melt 5 grams of ice?
To calculate this, we can use the formula: energy needed = mass * heat of fusion. The heat of fusion for ice is 334 J/g. Thus, the energy needed to melt 5 grams of ice is 5 grams * 334 J/g = 1670 Joules.
How many joules of heart are needed to melt 65.77 g of ice at 0 c?
To melt ice at 0°C, 333 J/g of heat is needed. Therefore, to melt 65.77 g of ice, you would need 65.77 g * 333 J/g = 21914.41 J or 21.91 kJ of heat.
The heat needed to melt one gram of a solid at its melting point is what?
The heat needed to melt one gram of a solid at its melting point depends on the heat of fusion value of the solid. To melt one gram of ice, for example, would require 334 J.
How many photons at 660 nm must be absorbed to melt 5.0 x 10 x10 g of ice?
To calculate the number of photons needed to melt the ice, you would need to determine the energy required to melt the ice and then convert that energy into photons at 660 nm. This involves calculating the energy required to melt the ice using the heat of fusion of ice and then dividing that by the energy of a photon at 660 nm.
