when the thermal energy is the energy contained within a system that is responsible for its temperature.  

and when the thermal energy  is can be determined by this formula:

q = M * C *ΔT

when q  is the thermal energy

and M is the mass of water = 100 g 

and C is the specific heat capacity of water = 4.18 joules/gram.°C

and T is the difference in Temperature = 50 °C

So by substitution:

∴ q = 100 g * 4.18 J/g.°C * 50

   = 20900 J  = 20.9 KJ

Explanation:

Thermal energy is defined as the internal energy of a substance or object which is due to kinetic energy of its atoms or molecules.

Relation between heat energy, mass and temperature is as follows.

                          q = [tex]m \times C \times \Delta T[/tex]

where,           m = mass

                      C = specific heat

               [tex]\Delta T[/tex] = change in temperature

It is given that mass is 100 g and temperature change is [tex]50^{o}C[/tex]. Specific heat of water is 4.18 [tex]J/g ^{o}C[/tex].

Therefore, calculate the energy as follows.

                      q = [tex]m \times C \times \Delta T[/tex]

                         = [tex]100 g \times 4.18 J/g ^{o}C \times 50^{o}C[/tex]

                         = 20900 J

Thus, we can conclude that thermal energy of water for given values is 20900 J.
