Which object has the most thermal energy?

 - a 375-gram bath towel at a temperature of 4°C
 - a 375-gram bath towel at a temperature of 20°C
 - a 375-gram bath towel at a temperature of 25°C
All three bath towels have the same mass but different temperatures. Since the 25°C towel is the hottest, it has the most thermal energy.
