The temperature changes over time when ice is heated from -5°c until it boils and evaporates
The temperature of the ice will increase gradually as it is heated until it reaches its melting point of 0°C. From this point, the temperature will remain constant at 0°C until all of the ice has melted into water.
Once all the ice has melted, the temperature of the water will begin to increase again as it is heated. The water will continue to increase in temperature until it reaches its boiling point of 100°C.
At the boiling point, the water will start to boil and evaporate, however, the temperature will remain at 100°C until all the water has evaporated. As steam evaporates, the temperature will no longer rise, but the pressure within the container will increase due to the buildup of steam.
It is important to note that the temperature changes described above apply to distilled water at a standard atmospheric pressure of 1 atmosphere (101.325 kPa). Other factors such as pressure and impurities in the water may affect the temperature changes during heating.
To answer that question in a step-by-step manner, let's break it down into stages:
Stage 1: Heating ice from -5°C to 0°C (Melting Point)
1. At -5°C, the ice exists in a solid state.
2. As heat is applied, the temperature starts to rise towards 0°C.
3. At 0°C, the ice reaches its melting point, and phase change occurs from solid to liquid.
4. During this phase change, even though heat is continuously applied, the temperature remains constant at 0°C until all the ice has melted.
Stage 2: Heating water from 0°C to 100°C (Boiling Point)
5. Once all the ice has melted into water, the temperature starts to rise again.
6. As heat is continuously applied, the temperature of the water increases up to 100°C.
7. At 100°C, the water reaches its boiling point and starts to vaporize.
8. During the phase change from liquid to gas, even though heat is still being added, the temperature once again remains constant at 100°C until all the water has vaporized.
Stage 3: Heating water vapor above 100°C
9. Once all the water has vaporized, the temperature begins to rise again.
10. The water vapor, now in a gaseous state, can continue to increase in temperature as more heat is added.
Please note that the exact temperatures and times may vary based on external factors such as pressure, impurities in the water, or the type of container used. The step-by-step description above provides a simplified outline of the temperature changes when ice is heated until it boils and evaporates.
