The quantity of heat required to evaporate 1 kg of a saturated liquid is called Specific heat 1 Kcal Sensible heat Latent heat TRUE ANSWER : ? YOUR ANSWER : ?
Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse The strong base and strong acid reacts completely TRUE ANSWER : ? YOUR ANSWER : ?
