Calculate the energy transferred when 5 kg of water condenses at 100°C. The specific latent heat of vaporisation for water is 2,260,000 J/kg (Changes of state and specific latent heat) (Changes of state and specific latent heat; equation and unit focus: Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known) (Changes of state and specific latent heat; equation and unit focus: Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known) ? P43-064 Changes of state and specific latent heat checkpoint

The correct answer is 11,300,000 J ? P43-064 density measurement and calculation.

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. This question asks: Calculate the energy transferred when 5 kg of water condenses at 100°C. The specific latent heat of vaporisation for water is 2,260,000 J/kg (Changes of state and specific latent heat) (Changes of state and specific latent heat; equation and unit focus: Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known) (Changes of state and specific latent heat; equation and unit focus: Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known) ?. The correct response is 11,300,000 J ? P43-064 density measurement and calculation, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Changes of state and specific latent heat, the marking point should connect directly to calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Internal energy and energy transfers, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 399 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
