If you are making maggie but its taking time because you have kept the temperature slightly lower than whats required ,so you want to speed up the process beacuse you are really hungry,you know that whole maggie,water and masala setup weighs 100 gms and specific heat is 0.9,you need 900 calories of heat more to make the maggie ,by how much amount you should increase the temperature?
10℃
Q= mass x specific heat x change in temperature
900=100 x 0.9 x temperature change
temperature change =10 ℃
