Q = ?
Cp = 0.450 j/g°C
Δt = 49.0ºC - 25ºC => 24ºC
m = 55.8 g
Q = m x Cp x Δt
Q = 55.8 x 0.450 x 24
Q = 602.64 J
hope this helps!

Explanation:
Thermal energy is the energy possessed by an object by virtue of its temperature. The hotter the substance, the more its molecules vibrate, and therefore the higher its thermal energy.
Thermal energy refers to the sum of kinetic, potential, vibrational ,electronic and rotational energies of the object.
For bodies at same temperature, the body with more molecules will have more thermal energy due to more collisions.
