- 2. This video is tailored especially for students preparing for Engineering Mathematics 1st semester, VTU syllabus Consider subscribing to my channel http://lnnk.in/@mathmadeeasy22
- 4. We learn about LR circuits and Newtons law of cooling and how to apply these to problems.
- 5. Newtons law of cooling states that the rate of change of temperature of a body is proportional to the difference between the temperature of the body and that of the surrounding medium.
- 11. Question 1 A bottle of water at a room temperature of 72 degrees F is refrigerated where the temperature is 44 degrees F. After half an hour, the water is cooled to 61 degrees F. What is the temperature of the water after half an hour What is the time taken for the water to cool to 50 degrees F
- 18. Question 2 Water at temperature 10 degrees Celsius takes 5 minutes to warm up to 20 degrees Celsius at room temperature 40 degrees Celsius. Find the temperature after 20 minutes.
