3 beakers are being heated (small, medium and large). consider the first two. both beakers are filled with water and heated for 10 minutes. after about 3 minutes the water in the small beaker the water in the small beaker is boiling; after 8 minutes the water in the large beaker is also boiling.
draw a graph that could show the change in temperature for the small beaker.
draw a graph that could show the change in temperature for the large beaker.
compare and contrast what is happening in both of the graphs using as much scientific detail as posssibe.

To draw the graphs, we need to understand the changes in temperature for both the small and large beakers over time. Let's start with the small beaker.
Graph for the Small Beaker:
On the x-axis of the graph, we'll plot time in minutes, and on the y-axis, we'll indicate the temperature in degrees Celsius.
To begin, at 0 minutes, the temperature of the water in the small beaker is at room temperature. As the water is heated, the temperature steadily rises. At around 3 minutes, the water starts to boil, so the temperature remains constant at the boiling point of water, which is approximately 100 degrees Celsius.
Since we know the boiling point is maintained after 3 minutes, we can represent this on the graph as a horizontal line at 100 degrees Celsius.
Now let's move on to the large beaker.
Graph for the Large Beaker:
Similar to the small beaker graph, the x-axis represents time in minutes, and the y-axis represents the temperature in degrees Celsius.
At 0 minutes, the temperature of the water in the large beaker matches the room temperature, just like the small beaker. As time passes and the beaker is heated, the temperature gradually increases. However, in this case, the water takes longer to boil.
After approximately 8 minutes, the water in the large beaker reaches its boiling point and starts boiling. So, from that point onwards, the temperature remains constant at 100 degrees Celsius, just like in the small beaker.
When we plot this on the graph, we will also show a horizontal line at 100 degrees Celsius starting from the 8th minute onward.
Comparing and Contrasting the Graphs:
Both graphs show an increase in temperature as time progresses until the water in each beaker reaches its boiling point. Upon reaching the boiling point, the temperature remains constant for both beakers.
The key difference lies in the time taken for the water to start boiling. In the small beaker, it starts boiling after around 3 minutes, while it takes approximately 8 minutes for the large beaker to reach that point.
This discrepancy can be attributed to the different volumes of water in each beaker. The small beaker has less water compared to the large beaker. As a result, it requires less time and energy to heat up to the boiling point. In contrast, the large beaker requires more time and energy to heat all the water molecules to the boiling point.
Understanding these differences helps us comprehend the relationship between the amount of water being heated and the time it takes to reach its boiling point.
