Question

a 500g sample of. water at 53 degree celsius is cooled down "-7" degree. celsius how much energy is removed

**Graph and Model Descriptions:** **B3. Use a graph to depict changes in temperature over time. (Graph)** The graph illustrates temperature changes over time. It includes various segments: an inclined line marked "th," a horizontal line labeled "ph," and another inclined line marked "th." These segments likely represent heating phases with temperature increases (th) and a phase change at constant temperature (ph). The y-axis is labeled "-7," suggesting a temperature scale, and the x-axis represents time. **A3. Use a graphical model to show how energy is conserved during a series of phase changes. (LOL)** The graphical model includes a series of representations showing energy conservation: - Alternating symbols of rectangles and circles suggest different states of matter or energy levels. - Arrows indicate transitions between these states, possibly representing energy flow or phase changes. **Calculation Section:** **B1. Calculate the amount of energy transferred for a change in temperature.** Includes the variables "500g" (likely referring to the mass of a substance) used for calculating energy transferred during a temperature change. **B2. Calculate the amount of energy transferred for a change in phase.** This section is left open for calculations regarding energy transfer during a phase change. **Descriptive Section:** **A2. Describe how changes in energy at the macroscopic level affect the motion and arrangement of particles. (Particle Diagram)** The section is intended for explaining the effects of energy changes on particle motion and arrangement, with space left for a particle diagram to illustrate these concepts. This content is designed to guide students in understanding thermal and phase energy concepts through visual and computational analysis.
