draw a temperature time plot for ice-steam transformation
How much water? What heating rate?
Temperature remains 100 C while it boils away. It rises approximately linearly with time before that, depending upon where you place the thermometer.
You will have to draw your own plot.
To draw a temperature-time plot for the ice-steam transformation, we need to understand the process of phase change and the associated temperature changes.
The ice-steam transformation involves the conversion of ice to steam through the addition of heat. Let's break down the process into four stages:
1. Stage 1: Heating the ice (solid) to its melting point:
At the start, we have ice at a temperature of -20°C (or any temperature below its melting point). As we add heat to the ice, its temperature increases linearly until it reaches its melting point. The specific heat capacity of ice is needed to calculate the temperature increase.
2. Stage 2: Melting the ice (solid) at a constant temperature:
Once the ice reaches its melting point (0°C), its temperature remains constant while it undergoes a phase change from solid to liquid. During this stage, the added heat is used to break the intermolecular bonds holding the ice molecules together rather than increasing the temperature.
3. Stage 3: Heating the water (liquid) to its boiling point:
After all the ice has melted, the temperature of the water starts rising again as heat is added. The water's temperature increases linearly until it reaches its boiling point. The specific heat capacity of water is needed to calculate the temperature increase.
4. Stage 4: Vaporizing the water (liquid) at a constant temperature:
Once the water reaches its boiling point (100°C), its temperature remains constant while it undergoes a phase change from liquid to steam. The added heat is used to transform the water molecules into water vapor.
To draw the temperature-time plot, you'll need to determine the temperatures at various time intervals for each stage. This can be done by considering the specific heat capacities, heat transfer rates, and mass of the substance undergoing the phase change.
Remember that the slope of the temperature-time plot will be steeper during heating stages (Stages 1 and 3) and flat during phase change stages (Stages 2 and 4).
Once you have calculated the temperatures at different time intervals for each stage, you can plot them on a graph with time on the x-axis and temperature on the y-axis.
