How much heat energy in megajoules is needed to convert 7 kilograms of ice at -9c to water at 0c?
To convert 7 kilograms of ice at -9°C to water at 0°C, you need to calculate the energy required for each phase change. First, calculate the energy to raise the ice temperature from -9°C to 0°C using the specific heat capacity of ice. Then, calculate the energy required to melt the ice into water using the latent heat of fusion of ice. The total energy will be the sum of these two values.
What is the energy required to melt a solid into a liquid called?
The energy required to melt a solid into a liquid is called the heat of fusion or enthalpy of fusion. It represents the amount of energy needed to overcome the intermolecular forces holding the solid together and transition it into a liquid state.
What is the energy required to melt a solid at its melting point?
The energy required to melt a solid at its melting point is known as the heat of fusion. This energy is used to break the bonds between the solid particles so they can move freely as a liquid. The amount of energy needed varies depending on the substance.
How much energy would be required to melt 32.0 g of ice?
The amount of energy required to melt ice can be calculated using the equation: energy = mass of ice * heat of fusion. The heat of fusion for ice is 334 J/g, so for 32.0 g of ice, the energy required would be 32.0 g * 334 J/g = 10,688 J.
How much energy is required to melt 2kg of gold?
To melt 2 kg of gold, it would require approximately 66,190 Joules per gram. Therefore, for 2 kg of gold, the total energy required would be around 132,380,000 Joules.
How much energy is required to melt 2 kg of copper Use the table below and this equation Q mLfusion.?
414 kJ
Can wood be use to melt copper?
No, wood cannot be used to melt copper because the temperature required to melt copper (1,984°F or 1,085°C) is much higher than the ignition point of wood (around 572°F or 300°C). To melt copper, a heat source such as a furnace or a torch that can reach the required temperature must be used.
How much energy is required to melt 10g of ice?
The energy required to melt ice is known as the heat of fusion, which is about 334 joules per gram. Therefore, it would take approximately 3340 joules of energy to melt 10g of ice.
The energy required to melt one gram of a substance is known as what?
The energy required to melt one gram of a substance is known as the heat of fusion.
How much energy is required to melt 56g?
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
What does the latent heat of fusion?
The energy required to melt a substance
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
What is the amount of energy required to raise the temperature of 1 kilograms of a substance by 1 kelvin is called?
Specific heat is the amount of heat needed to melt one kilogram of a substance...heat of fusion
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
How many btu's are required to melt copper?
To melt copper, approximately 1,200 BTUs (British Thermal Units) are required for each pound of copper. This value accounts for both the heat needed to raise the temperature of the copper to its melting point (about 1,984°F or 1,085°C) and the latent heat of fusion. The exact amount can vary slightly based on the specific conditions and purity of the copper.
What energy is required to melt 18.2g of water?
The energy required to melt a substance is known as its heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, to melt 18.2g of water, the energy required would be 18.2g x 334 J/g = 6078.8 J.
What is required to cause something to melt?
Melting is a change of state of a substance caused by an increase in thermal energy, so heat is required to melt a substance.
