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.

What is the melting point of californium?
The melting point of californium is: 900 0C.
How much ergy is required to melt 2 kg of gold?
The specific heat capacity of gold is 0.128 J/g°C, and the heat of fusion of gold is 63 J/g. To calculate the energy required to melt 2 kg of gold, you would first need to convert the mass to grams (2000 g). The energy required would be the sum of the energy needed to raise the temperature from the melting point to the melting point and the energy needed for the phase change.
What is the melting point of a balloon?
The mass of the balloon depends on its size. For small sized balloon, weighing scale can be used to calculate the mass. Anything that has mass will have gravitational force acting on it.

What formula can be used to calculate how much additional energy is needed to reach the melting point of stainless steel taking ambient temperature into account?
You simply subtract the melting point of steel, minus the ambient temperature.
How do you calculate the melting point of a substance?
The melting point of a substance is determined by heating it gradually and recording the temperature at which it changes from a solid to a liquid state. This temperature is the melting point.
The melting point of a block of choclate?
Chocolate is a mixture and therefore doesn't have a well defined melting point. The temperature at which any given block of chocolate melts depends upon its composition.
How can you calculate melting point of subliming solid?
Impossible to calc any melting or boiling points.
To calculate the amount of heat absorbed as a substance melts what information is not needed?
To calculate the amount of heat absorbed as a substance melts, you do not need information about the substance's boiling point or its specific heat capacity in the liquid state. The key parameters needed are the substance's heat of fusion (melting) and the mass of the substance melting.
What is goals boiling and melting point?
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.

1) they have high melting and boiling point
How do you calculate melting point of methane?
The melting point of methane is -182.5 degrees Celsius or -296.5 degrees Fahrenheit. This value is experimentally determined by observing the temperature at which methane transitions from a solid to a liquid state.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
How do you calculate melting points and boiling points by using enthalpy and entropy?
The melting point and boiling point of a substance are related to its enthalpy of fusion and vaporization, respectively, and its entropy of fusion and vaporization. The melting point is where the solid and liquid phases are in equilibrium, while the boiling point is where the liquid and vapor phases are in equilibrium. By analyzing the balance between enthalpy and entropy changes during phase transitions, you can predict and calculate melting and boiling points.
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.
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.
