Question

What is Latent heat??????And its SI UNIT????​

Answer 1

$\huge\bf\red{AnswEr:-}$

$\bigstar$Latent Heat is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change.

$\bigstar$It is defined through the formula Q = mL. It is often just called as the "latent heat" of the material.

$\bigstar$It uses the SI unit joule per kilogram [J/kg].

★LATENT HEAT :

➾The amount of energy it takes to melt or boil a certain amount of material is called a latent heat.

☞Latent heat can be calculated using the following formula:

➯Q = mΔH

★where,

Q⟶ the quantity of heat in Joules (J)

m⟶the mass of the material in grams

ΔH⟶the latent heat of the substance in J/g

★SI UNIT:

➣The SI unit of latent heat is Joule.
