Understanding heat has changed metallurgy, materials science, mining, refineries, a large variety of chemical reactions, semiconductor electronics, meteorology, and transportation.

What is Heat?

  • Heat is a form of energy that is transferred from one body to another due to a temperature difference.
  • It can be transferred through three modes: conduction, convection and radiation.

 How Does Heat Animate Engines?

  • Internal Combustion Engines: Heat from combustion of fuel in the engine cylinders is converted into mechanical energy, which powers the vehicle.
  • Heat exchangers: Heat is transferred from the engine to the cooling system, which helps maintain the engine's optimal operating temperature.

How Does Heat Cause Global Warming?

  • Greenhouse effect: Heat from the sun is trapped in the Earth's atmosphere by greenhouse gases, leading to an increase in global temperatures.
  • Human activities: Human activities such as burning fossil fuels and deforestation release large amounts of carbon dioxide and other greenhouse gases, exacerbating global warming.
