chem12 Thermodynamics -- thermal energy question

1. The problem statement, all variables and given/known data

Which would have a higher amount of thermal energy:

cup of tea @ 75°C OR bathtub of water @ 50°C

2. Relevant equations

q=mcΔT

3. The attempt at a solution

I know both are made of water with a specific heat capacity of 4.184 J/g°C. I don't know the differences in temperatures, but the fact that the tub has a greater mass probably has something to do with it, not sure what though

Any help is appreciated. Thankyou!!! :)

Thermal energy is simply U=mcT and only the heat transfer that is q=mcΔT. So you don't have to bother about the difference in temperature.
