Question

what is indicated by time - temperatures graph in above activity

Answer 1

By plotting a time - temperature graph one can easily find out the temperature in unit time.

He or she also gets the idea about the nature of the graph i.e. whether the temperature is increasing linearly or exponentially or decreasing linearly or exponentially or reamins constant with the time.

It must be noted that the scale used in the graph to plot the data should be mentioned in the graph.

Answer 2

A time-temperature graph has temperature on the vertical y-axis and time along the horizontal x-axis. Temperature will be in degree Celsius (C)

By recording time and temperature, you can easily figure out the “degrees per minute” that the middle is heating up and make a fairly accurate prediction of when it will be done.
