The heat of vaporization of gold is 158 kJ/kg. To find the total energy required to vaporize 2 kg of gold, you can use the equation: Energy = mass * heat of vaporization. Substitute the values to get: Energy = 2 kg * 158 kJ/kg = 316 kJ. Therefore, 316 kJ of energy is required to vaporize 2 kg of gold.

What is the latent heat of sublimation?

No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.


How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C Use the table below and this equation Q mcT. Substance Specific Heat Capacity Liquid water 4.186 Ice 2.11 Air 1.00?

The specific heat capacity of iron is about 0.45 J/g°C. To raise the temperature of 3 kg of iron by 5°C, you would use the equation Q = mcΔT, where m is the mass (3 kg), c is the specific heat capacity (0.45 J/g°C), and ΔT is the change in temperature (5°C). Therefore, the energy required would be around 6,750 Joules.


The form of energy in nuclear reaction?

The form of energy in a nuclear reaction is primarily released in the form of electromagnetic radiation (gamma rays) and kinetic energy of the reaction products. This energy is a result of the conversion of mass into energy as dictated by Einstein's famous equation E=mc^2.


In the equation for elastic potential energy below what is represented by the symbol k Ee and frac12 and times k and times e and sup2?

The symbol "k" represents the spring constant. "Ee" stands for elastic potential energy. "frac12" means one-half in the context of the equation. "k" multiplied by "e" and squared represents the extension or compression of the spring from its equilibrium position.


Can the gravitaional potential energy of an object be negative?

Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.

How much energy is required to vaporize 2 kg of copper Use the table below and this equation?

To calculate the energy required to vaporize 2 kg of copper, you need to use the specific latent heat of vaporization for copper, which is approximately 300,000 J/kg. The total energy (Q) can be calculated using the equation Q = m * L, where m is the mass (2 kg) and L is the latent heat of vaporization (300,000 J/kg). Thus, Q = 2 kg * 300,000 J/kg = 600,000 J. Therefore, 600,000 joules of energy is required to vaporize 2 kg of copper.
