It is possible that the heating system is broken and unable to exchange heat anymore. This could be due to a malfunction in the heating unit, a blockage in the system, or a lack of proper maintenance. It is important to have a professional inspect the heating system to determine the cause of the issue and make any necessary repairs. **

When a steel ball is submerged underwater, heat exchange occurs through conduction. The water molecules in contact with the surface of the steel ball gain heat energy from the ball, causing them to move faster and collide with neighboring molecules, transferring the heat. This process continues throughout the water, gradually spreading the heat away from the steel ball. Additionally, convection currents may also play a role in the heat exchange, as the warmer water near the steel ball rises and is replaced by cooler water, creating a continuous flow of heat transfer. **

When a steel ball is submerged underwater, heat exchange occurs through conduction. The steel ball will absorb or release heat depending on the temperature difference between the ball and the surrounding water. As the steel ball comes into contact with the water, heat is transferred from the water to the ball or vice versa, until thermal equilibrium is reached. This process continues until the temperature of the steel ball matches that of the surrounding water. **

Exchange students are not considered diplomats. While they may represent their home country in a cultural exchange program, they do not have the official status or responsibilities of a diplomat. Exchange students typically participate in educational and cultural programs to learn about a new country and share their own culture, but they do not engage in diplomatic negotiations or represent their country's government. **
