if yes, explain how and why
if no, explain their differences

Latent heat is a kind of internal energy.(internal energy=kinectic energy+potential energy)
'.'when latent heat is absorbed or given out , PE of the substances should change and hence its internal energy changes.
參考: myself
我唔係好勁
不過根據我既phy知識
首先.heat一定唔係internal energy,因為佢只係energy transfer
between 2 objects
而internal energy雖然係sum of kinectic energy and potential energy
但係佢係 the energy stored in body
而latent heat 係heat既一種( the energy need to change the substance to other
state without any temperature change)
最後,我認為latent heat唔係internal energy
信不信由你,不過我希望樓上既大大先岩
我見佢好似答左好多phy問題
希望佢唔係扮醒,真係幫到大家,更加唔好害到人,thx= =
Yes. Internal energy of an object is the totoal of its kinetic and potential energies. Latent heat contributes to its potential energy, so it is a kind of internal energy.
