Question

Explain is latent heat ?
​

Answer 1

Answer:

the heat involving inside a substance changing its state's is called latent heat

Answer 2

$\huge{ \orange{ \underline{ \overline{ \boxed{ \blue{ \mathbb{ANSWER}}}}}}}$

LATENT HEAT :

☆ It is the heat required to convert 1 kg of substance from one state to another without changing in temperature.

There are two types of Latent Heat.

(i) Latent Heat of Fusion : It is the process of conversion of unit mass of a substance from solid to liquid state at constant temperature.

(ii) Latent Heat of Vaporisation : it is the amount of heat required to convert unit mass of liquid completely into vapour state without any change in temperature.

$\boxed {\sf{\red{EXTRA \: \: POINTS : }}}$

$\sf{ \star \: \underline\orange{Latent \: Heat \: of \: Fusion \: of \: Ice \: : }}$$\sf{\underline\orange{80 \: Cal/ g. \: or \: 3.33 \times {10}^{5} J/ kg}}$

$\sf{ \star \:\underline\orange{Latent \: Heat \: of \: vaporisation \: of \: water\: : }}$ $\sf{\underline\orange{540 \: Cal/ g. \: or \: 22.6 \times {10}^{5} J/ kg}}$
