A falling object has caused a bucket of water to increase in temperature. The water has a mass off 2000g. If the change in temperature is 1.5C, then what is the change in thermal energy?

m is the mass of the given substance, c is the specific heat and ΔT is the temperature difference

From the question, it is clear that,
m = 2kg, c = 4.18J/kg°C, ΔT = 1.5°C
The formula for thermal energy is
Q = mcΔT
Q = 2×4.18j\kg×1.5 = 12.54J
