A hot object will have more kinetic energy which means faster moving particles. A cold object will have less kinetic energy which means slower moving particles.
We are aware that many forms of energy can be converted into one another in accordance with the law of conservation of energy. To put it another way, thermal energy can be changed into kinetic energy and vice versa.

[tex]KE= \frac{1}{2} m v^{2}[/tex] so as Kinetic Energy increases speed of particles also increase.
