FAQs on Visual Worksheet: Energy Transformations - Science & Technology for UPSC CSE

1. What are energy transformations?
Ans.Energy transformations refer to the process of changing energy from one form to another. For example, when we use a battery-powered device, the chemical energy stored in the battery is transformed into electrical energy, which then powers the device.
2. Can you provide examples of energy transformations in everyday life?
Ans.Yes, there are many examples of energy transformations in everyday life. For instance, in a toaster, electrical energy is transformed into thermal energy to heat and toast the bread. Similarly, in a car engine, chemical energy from fuel is converted into mechanical energy to move the vehicle.
3. How does the law of conservation of energy relate to energy transformations?
Ans.The law of conservation of energy states that energy cannot be created or destroyed; it can only be transformed from one form to another. This means that in any energy transformation, the total energy before and after the transformation remains constant, though it may change forms.
4. What role do energy transformations play in natural processes?
Ans.Energy transformations are essential in natural processes such as photosynthesis, where plants convert solar energy into chemical energy. This chemical energy is then used to create food, illustrating how energy transformations support life on Earth.
5. What are the different types of energy involved in transformations?
Ans.The different types of energy involved in transformations include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in bonds of molecules), electrical energy (flow of electric charge), and nuclear energy (stored in atomic nuclei). Each type can be transformed into others in various processes.
