mass defect gives rise to energy, can energy as heatalso increase mass ? like in this ques second part... The heat produced when petrol is burnt is about 47 MJ/kg. a)If 1 kg of petrol is burnt in a closed chamber in the presence of sufficient oxygen, by what amount is the final mass different from the initial mass of the chamber? b) If the chamber in which the petrol is burnt is insulated, so that the heat produced stays inside the chamber, then by how much would the mass of the chamber change?
