To calculate the heat needed to vaporize 2.72 moles of nitrogen, you can use the heat of vaporization for nitrogen, which is approximately 199 kJ/mol. Multiply the number of moles by the heat of vaporization:
[ Q = 2.72 , \text{moles} \times 199 , \text{kJ/mol} \approx 541.28 , \text{kJ} ]
Therefore, approximately 541.28 kJ of heat is needed to vaporize 2.72 moles of nitrogen.

How much energy is needed to vaporize 2 kg of aluminum?
To vaporize aluminum, you need to consider its heat of vaporization, which is approximately 10,700 kJ/kg. For 2 kg of aluminum, the total energy required would be 2 kg × 10,700 kJ/kg, equating to about 21,400 kJ. Therefore, around 21.4 million joules of energy is needed to vaporize 2 kg of aluminum.
How much energy is needed to melt 25.4grams of l2?
To calculate the energy needed to melt 25.4 grams of I2 (iodine), you can use the formula: energy = mass x heat of fusion. The heat of fusion for iodine is 15.52 kJ/mol. First, find the molar mass of I2 (253.8 g/mol) and then convert the mass to moles. Finally, multiply the moles by the heat of fusion to get the energy needed.

How much energy is needed to vaporize 2 kg of gold?
The energy required to vaporize a material can be calculated using its heat of vaporization. For gold, the heat of vaporization is approximately 330 kJ/mol. Since gold has a molar mass of 196.97 g/mol, 2 kg of gold is equal to 10.15 moles. Therefore, the energy needed to vaporize 2 kg of gold is approximately 3.35 MJ.
Why the time needed to vaporize a sample is greater than the time needed to melt a sample?
The amount of time depends on the latent heat of vaporisation and the latent heat of melting.
How much heat is needed to vaporize 7.24 ml of sweat from your skin at twenty five degrees Celsius?
To calculate the heat needed to vaporize sweat, you would need to know the specific heat of vaporization of sweat. Once you have that information, you can use the formula Q = mL, where Q is the heat needed, m is the mass of the substance (converted from volume using its density), and L is the specific heat of vaporization.
