- Hydroelectric energy, solar energy and wind energy are called renewable energies Hydroelectric, solar and wind energy are called renewable because their sources are replenished naturally and will not run out however much... 1
- It is absolutely necessary to control the fission reaction in nuclear power plants. The fission reaction must be controlled because an uncontrolled chain reaction releases enormous energy in a very short time, which can caus... 1
- The construction of turbine is different for different types of power plants. The construction of the turbine differs because the substance that turns it and its pressure and speed are different in different power plan... 1
- Explain with diagram step-by-step energy conversion in d. Hydroelectric power plant In a hydroelectric power plant: potential energy of stored water → kinetic energy of flowing water → mechanical energy of turbine → electric... 1
- Explain with diagram step-by-step energy conversion in c. Solar thermal power plant In a solar thermal power plant: solar energy → heat energy → kinetic energy of steam → mechanical energy of turbine → electrical energy. Ste... 1
- Explain with diagram step-by-step energy conversion in b. Nuclear Power Plant In a nuclear power plant: nuclear energy → heat energy → kinetic energy of steam → mechanical energy of turbine → electrical energy. Steps:... 1
- Explain with diagram step-by-step energy conversion in a. Thermal power plant In a thermal power plant: chemical energy of coal → heat energy → kinetic energy of steam → mechanical energy of turbine → electrical energy... 1
- What are the advantages and limitations of solar energy? Solar energy is free, renewable and pollution-free, but it is available only in daytime, depends on the weather and needs costly equipment a... 1
- How can we get the required amount of energy by connecting solar panels? By connecting solar panels in series (to increase voltage) and in parallel (to increase current), we can make a solar array that gives the r... 1
- Saving energy is the need of the hour. Saving energy is the need of the hour because the demand for energy is rising fast while fossil fuel reserves are limited and their use poll... 1
- Energy obtained from fossil fuels is not green energy Energy from fossil fuels is not green energy because burning them pollutes the environment and the fuels are non-renewable. Burning coal, pe... 1
- What is meant by green energy? Which energy sources can be called as green energy sources and why? Give example. Green energy is energy obtained from sources that do not harm the environment, that is, sources which produce no (or very little) pollution... 1
- Explain the difference Thermal electricity generation and solar thermal electricity generation Both use heat to make steam that turns a turbine; the difference is the source of the heat. Thermal electricity generationSolar thermal elec... 1
- Explain the difference Conventional and Non-conventional Sources of energy. Conventional sources are the traditional, mostly non-renewable sources used on a large scale (coal, petroleum, natural gas); non-conventiona... 1
- Solve the following crossword puzzle. a. Maximum energy generation Answers: a. Thermal (coal); b. Solar (or wind); c. Green; d. Kinetic; e. Potential a. Most of India's electricity is generated in thermal po... 1
- Which type/types of power generation involve maximum number of steps of energy conversion? In which power generation is the number minimum? Maximum steps: thermal (coal), nuclear and solar thermal power plants. Minimum steps: solar photovoltaic cells. Follow the chain of energy c... 1
- Consider a circular coil of wire carrying current I, forming a magnetic dipole. The magnetic flux through an infinite plane that contains Answer: (a) φ_i = -φ₀ Magnetic field lines always form closed loops (there are no magnetic monopoles), so the net magnetic flux through any... 1
- Two moles of an ideal gas with Cp/Cv = 5/3 are mixed with 3 moles of another ideal gas with Cp/Cv = 4/3. Answer: (c) 1.42 For a mixture, add the heat capacities of the gases. For an ideal gas, C_V = R/γ - 1 and C_P = γ C_V . Gas 1 ( n₁ = 2,\ γ₁... 1
