Which object has the most thermal energy?

 - a 350-gram mug of cider at a temperature of 75°C
 - a 350-gram mug of cider at a temperature of 54°C
 - a 350-gram mug of cider at a temperature of 53°C
All three mugs of cider have the same mass but different temperatures. Since the 75°C mug of cider is the hottest, it has the most thermal energy.
