How does heat animate engines and global warming?

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.
