Three of the statements are true. Which is NOT?
Temperature (*C)
(6.5, 26)
Time (min)
CLEAR
CHECK
The temperature of the liquid is increasing at a constant
rate.
At this rate, the temperature fill rise 60° in a quarter hour.
The temperature of the liquid changed at a unit rate of 4
per minute
At this rate, it would take less than 10 minutes for the
temperature of the liquid to rise 52.
