Firing a piece of pottery in a kiln takes place at different temperature for different amounts of time. The graph shows the temperature in a kiln while firing a piece of pottery (note: oven was preheated) a. Determine the time interval during which the temperature in the kiln showed the greatest rate of change. 1500 1500 (8.95, 1920) (4.65, 1680)- (2.5, 1300) Temperature (F) 1000 (1.5, 1000) 500 (0, 250) b. Determine the time interval during which U 2 4 6 the temperature in the kiln showed the least 8 10 X rate of change. Time (hours) 306acer Brust, Sully, and Kelly love to play Pokemon.
