How much heat energy in cal wil be obtained from 1.5kw heat
Answers
Answer:
Energy Produced = Power x Time
= 1.5kW x 1 hr
= 1.5kWh
The heater produces 1.5 kWh energy per hour.
Answer:
the heat energy obtained from 1.5 KW is = 357 cal.
Explanation:
Heat has constantly been a riddle. Antoine Lavoisier theorized that lukewarmness came from a substance with mass. That intended that lukewarm switch bothered the switch of a real substance among bodies. Unfortunately, Lavoisier s principle came now no longer supported through experimental observation, so an advanced description of warmth came demanded.
Heat has constantly been burdened with temperature, still, the cause is that lukewarmness and temperature are related. Temperature is a quantitative degree of hotness or coldness. Solids, liquids, and gases are made of atoms and molecules. When those atoms and molecules are transferring sluggishly, also the temperature of that substance could be low. The quicker the atoms and molecules move, the better the temperature. Heat is the entire electricity of those atoms and molecules as they move.
heat energy is defined by the flow of energy between two systems by means of kinetic energy.
H = W/J ( W= mechanical work done and J mechanical equivalent of heat)
according to the question;
H = 1.5KW/4.2Kcal
H = 1500/4.2
H = 357 cal.
heat energy obtained is 357 cal.
