Question

59. At constant pressure certain quantity of water at 24°C is heated. It was observed that the rise of temperature
was found to be 4°C per minute. Calculate the time required to rise the temperature of water to 100°C at
sea level by using formula.​

Answer 1

Answer:

Its from progression..

24°+28+32+----+100 This the series of A.p

Now take a=24 and d=4 and Tn=100 and then apply the formula

Tn=a+(n-1)d and substitute the values and you will get the answer n=20..
