The object at 50°C will have a higher kinetic energy.
Explanation:
Temperature is a measure of the average kinetic energy of the particles in an object. As you introduce more energy into the system (e.g. heat the object), the particles on average move faster because they have more kinetic energy.
Solid- molecules vibrate in place and tightly packed liquid-molecules fur shape of container and can slide past each other gas-molecules also fit shape of container and have the most room
