Latent heat
Joseph Black measured the temperature and realized after he heated ice to melt it that its water was no warmer. The heat had gone into the ice but only changed its state.
Scotch
Dr. Black was Scottish and discovered latent heat while working on commission for a Scotch distillery to determine ideal quantities of fuel and water for distilling whisky.
Latent stuff
Latent energy Latent sexuality Latent emotion Latent ability to please Latent sense of humor Latent desire for a pony Something latent in the eye of the beholder who hasn’t yet beheld Something latent in the ancient edifice a restoration could reveal A latent case of tuberculosis that hasn’t caused a cough I had always wanted to use the word ‘endothermic’ or something like it A drunk evening lay in the amber liquid lying in the glass
Latent heat is contrasted with sensible heat, which isn’t hidden, but can be felt.
