Give five differences between specific heat and latent heat
Answers
➡➡DIFFERENCE BETWEEN SPECIFIC AND LATENT HEAT
1.⏹latent heat is the heat that is being absorbed or released from a substance during a phase change.
⏺whereas specific heat is the heat which is independent of amount of substances.
2.⏹Latent heat changes don't cause temperature changes as they are absorbed or released
⏺ As its DEFINITION says, it cause temperature CHANGES based on the amount of substances consumed.
3.⏹Latent heat apply for phase undergoing phase change.
⏺Specific heat doesn't apply when substance is under going phase change..
4.⏹There are two types of latent heat
i . latent heat of fusion
ii. latent heat of vaporisation
⏺ It usually consist of only thermal regulation.
5.⏹ In latent heat , energy is absorbed to break hydrogen bond
⏺In specific heat, no energy is needed

Answer:
When a substance undergoes a phase change, the energy is absorbed or released as heat. Latent heat is the heat that is being absorbed or released from a substance during a phase change. This heat changes do not cause temperature changes as they are absorbed or released. The two forms of latent heat are latent heat of fusion and latent heat of vaporization. Latent heat of fusion takes place during melting or freezing, and latent heat of vaporization takes place during boiling or condensing.
Explanation:
Heat capacity is dependent on the amount of substance. Specific heat or specific heat capacity (s) is the heat capacity which is independent of the amount of substances. It can be defined as “the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius (or one Kelvin) at a constant pressure.” The unit of specific heat is Jg-1oC-1. The specific heat of water is very high with the value of 4.186 Jg-1oC-1. This means, to increase the temperature by 1 oC of 1 g of water, 4.186 J heat energy is needed. This high value encounters for the role of water in thermal regulation. To find the heat needed to increase the temperature from t1 to t2 of a certain mass of a substance following equation can be used.
q = m x s x ∆t
q = required heat
m = mass of the substance
∆t = t1-t2
Latent heat is the energy absorbed or released when a substance is undergoing a phase change. Specific heat is the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius (or one Kelvin) at a constant pressure.
