From room A, a thermometer is brought into room B with ambient temperature of 30 degrees C at t = 0. At t = 10 minutes, the temperature reading of the thermometer becomes 20 degrees C. Att= 20 minutes, the temperature reading becomes 25 degrees C and the thermometer is brought back to room A. How many minutes will it take for the thermometer to have its reading go back to 20 degrees C (after it was brought back to room A)? Use the concepts discussed in differential equations. Whenever needed, round-off values accurate to four significant figures after the decimal point. Attach File Browse Local Files Browse Content Collection
