The temperature 12

The temperature of a liquid was 25°C before it was warmed at a rate of 10°C per minute for 5 minutes. It was then cooled at 3.5°C per minute for 6 minutes. What was the temperature of the liquid after cooling?

Correct answer:

T =  54 °C

Step-by-step explanation:

T0=25 °C r1=10 °C/min t1=5 min  r2=3.5 °C/min t2=6 min  T=T0+r1 t1r2 t2=25+10 53.5 6=54°C
