Questions & Step-by-Step Solutions

If the latent heat of vaporization of water is 2260 kJ/kg, how much energy is required to convert 0.5 kg of water at 100°C to steam at 100°C?
  • Step 1: Identify the mass of water you want to convert to steam. In this case, it is 0.5 kg.
  • Step 2: Identify the latent heat of vaporization of water, which is given as 2260 kJ/kg.
  • Step 3: Use the formula to calculate the energy required: Energy required = mass * latent heat.
  • Step 4: Substitute the values into the formula: Energy required = 0.5 kg * 2260 kJ/kg.
  • Step 5: Perform the multiplication: 0.5 * 2260 = 1130 kJ.
  • Step 6: Conclude that the energy required to convert 0.5 kg of water at 100°C to steam at 100°C is 1130 kJ.
