Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.
<h3>What is thermal energy?</h3>
The energy contained by an object by virtue of heating is known as thermal energy.
Given is the mass of water m = 150 kg, Temperature change ΔT = (40 -20)= 20 °C
The specific heat of water Cp =4182 J/kg.°C
Heat transfer Q =m x Cp x ΔT
Q = 150 x 4182 x 20
Q = 12,546,000 J
Thus, Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.
