If 3.00 × 10⁶ J of energy is supplied to 0.90 kg of ice at 0 °C, how much of the ice will have melted? Assume the specific latent heat of fusion of ice is 3.34 × 10⁵ J kg⁻¹ (Changes of state and specific latent heat) ? P43-056 Changes of state and specific latent heat checkpoint

The correct answer is 0.75 kg ? P43-056 state-change particle arrangement.

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. This question asks: If 3.00 × 10⁶ J of energy is supplied to 0.90 kg of ice at 0 °C, how much of the ice will have melted? Assume the specific latent heat of fusion of ice is 3.34 × 10⁵ J kg⁻¹ (Changes of state and specific latent heat) ?. The correct response is 0.75 kg ? P43-056 state-change particle arrangement, because changes of state are explained by particle energy and arrangement. In Changes of state and specific latent heat, the marking point should connect directly to explain that energy transferred during a change of state changes particle potential energy rather than average kinetic energy. 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 423 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
