If the particles in the medium (solids, liquids, gases) can move fast by any reason , then the medium get Hot, and if the particles moves slowly it will get cold.
HOT means gain heat energy, COLD means loss heat energy.
Further, the kinetic energy of the particles in the medium results it’s temperature .
Year by Year our mother land fighting with pollution and global warming which was dumped by humans. The result is temperature increases nearly 1.5 degrees Celsius per year . The resources on earth is not increases as population increases. Hence, the unwanted energy will dumping into the atmosphere , it will pollute the nature. What we will give to the next generation?
Population is the biggest and number one problem on earth — isn’t it ?
