Sensible heat is the amount of heat, (molecular motion), you can measure with a thermometer. It’s the amount of heat you add or remove to a substance that changes a substance temperature but does not change the state of a substance.
Latent heat is heat added or removed that will change the state of a substance but does not affect the temperature of the substance. Water to steam is a change of state.
Example: We’ll look at a pot of water on a stove and see what happens. Using distilled water will give more accurate numbers
- The pot of water heats up from 40°F to 90°F. The water is getting nice and warm, but there’s no change of state (boiling/steam). So this is only sensible heat added
- As the pot of water continues to accept heat from the burners, the pot eventually reaches 212°F, the boiling point. There’s a change of state happening as the liquid water changes to steam. Even with heat still being applied to the pot of water, the pot will remain at 212°F. This heat energy being applied is the latent heat causing the change in state from liquid to vapor steam
Joto la hisia ni kiasi cha joto, (harakati ya molekuli), unaweza kupima na thermometer. Ni kiasi cha joto wewe kuongeza au kuondoa kwa dutu ambayo hubadilisha joto dutu lakini haina kubadilisha hali ya dutu. Joto la siri ni joto lililoongezwa au kuondolewa ambalo litabadilisha hali ya dutu lakini halitaathiri joto la dutu. Maji kuwa mvuke ni mabadiliko ya hali. Mfano: Tutaangalia chungu cha maji kwenye jiko na kuona nini kinatokea. Kwa kutumia maji ya distilled, unaweza kupata idadi sahihi zaidi, na kupanua joto la maji kutoka 40 ° F hadi 90 ° F. Maji ni kupata nzuri na joto, lakini hakuna mabadiliko ya hali (kuchemka / mvuke). Kwa hiyo, joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto la joto. Kuna mabadiliko ya hali yanayotokea wakati maji ya kioevu yanapobadilika kuwa mvuke. Hata kama joto bado ni kutumika kwa sufuria ya maji, sufuria itakuwa kubaki katika 212 ° F. Hii nishati ya joto kutumika ni joto latent kusababisha mabadiliko katika hali kutoka kioevu kwa mvuke mvuke
