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

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
