How much energy (in kJ) does it take to heat 1000L of water from 15 degrees * C to 25 degrees * C ?​

Heat Q is the thermal energy transferred from a hotter system to a cooler system that are in contact.

Q=m.Cp.ΔT (Eq.1)

The equation above relates the temperature or the temperature difference of a substance or fluid with the thermal energy required to transfer Heat (whether heating or cooling).

Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.

The thermal energy Q is calculated by the product of the mass of the substance (kg) by the specific heat of the substance or fluid (kJ/kg.k) by the temperature difference ΔT (.K) in degrees Kelvin.

Example: Heat output required to heat up 1000 litres of water from 5.C to 18.C (degrees Celsius).

Q=m.Cp.ΔT

Q = ~ 54,7kW

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
