A body is originally at 80c and cools down to 60c in 20min.If the temperature of the air is 40c find the temperature of the body after 40mins
Hello student,
In the question, it's mentioned that A body is originally at 80c and cools down to 60c in 20min.If the temperature of the air is 40c.
So, first DT/dt= 80-60/20=2.
So, after 40 minutes, 60-T/40= 2, so upon solving it seems that T= -20c.
So, the temperature of the body after 40mins is -20c.
