How much heat energy is necessary to raise the temperature of 5 KG water from 20°C 200°C

Answer»

y of heat required to raise 5 kg of water from 20 0C  to 1000C is given by the formula:Q=m×C×ΔT(Q is usually used to symbolize that heat required in a case like this.)For water, the value of .C  is 4.186Jg°C.So,Q=750×4.186×85=266858J=266.858kJDT = TEMPERATURE difference =100-20=80 0C.Answer is  266.858kj1 calorie = 4.18 Joules. THUS 4180 Joules of energy of heats required for  a Kilogram of water through just ONE degree  centigrade. So, we are to save  save energRead more on Brainly.in - brainly.in/question/6314388#readmore
