Which object has the most thermal energy?

 - a 280-gram bottle of water at a temperature of 40°F
 - a 280-gram bottle of water at a temperature of 72°F
 - a 280-gram bottle of water at a temperature of 45°F
All three bottles of water have the same mass but different temperatures. Since the 72°F bottle of water is the hottest, it has the most thermal energy.
