Give a sketch of temperature versus time graph of the heating process of the ice towater from – 10 oC to 110 oC

Here's a step-by-step guide to sketching a temperature versus time graph for the heating process of ice to water from -10°C to 110°C:

1. Draw your axes: The x-axis will represent time and the y-axis will represent temperature.

2. Mark your temperature scale on the y-axis: Start from -10°C (representing the initial temperature of the ice) and end at 110°C (representing the final temperature).

3. Plot the initial point: This will be at time = 0 and temperature = -10°C.

4. Draw a straight, diagonal line upwards from -10°C to 0°C: This represents the heating of the ice from -10°C to 0°C. The slope of this line represents the rate of heating.

5. Draw a horizontal line from 0°C to a certain point on the x-axis: This represents the phase change from ice at 0°C to water at 0°C. During this phase change, the temperature does not increase even though heat is being added.

6. Draw another straight, diagonal line upwards from the end of the previous line to 100°C: This represents the heating of the water from 0°C to 100°C.

7. Draw another horizontal line from 100°C to a certain point on the x-axis: This represents the phase change from water at 100°C to steam at 100°C. Again, the temperature does not increase during this phase change.

8. Draw a final straight, diagonal line upwards from the end of the previous line to 110°C: This represents the heating of the steam from 100°C to 110°C.

Remember, the length of the horizontal lines (representing phase changes) should be longer than the diagonal lines (representing heating) because phase changes require more time (i.e., more heat energy) than heating.
