Give reason:
a.Heat is a form of energy
b. Light is a form of energy
c. List four types of energies derived from the energy of the Sun.
Answers
Answer:
is this right?
Explanation:
a. Heat as a form of energy. Because all of the many forms of energy, including heat, can be converted into work, amounts of energy are expressed in units of work, such as joules, foot-pounds, kilowatt-hours, or calories.
b. light is the form of energy because it can help us to work anything as well as energy. light is very useful like sunlight. nowadays without light we cannot sleep in night in summers. in paper time without light we cannot study.so light is a form of energy.
c.i don't know
Explanation:
a. Heat is a form of energy
Ans - All of the many forms of energy, including heat, can be converted into work, amounts of energy are expressed in units of work, such as joules, foot-pounds, kilowatt-hours.Hence heat is a form of energy
b. Light is a form of energy
Ans- Light also contains such photons which are considered as the small packets of energy. Light travels from the Sun to Earth and from different light sources in the form of a wave thus they possess the kinetic energy which allow them to travel through space even where there is no air.
Thus, light is also a form of energy.
c. List four types of energies derived from the energy of the sun
Ans - Four types of energies drived from the energy of the sun:
Visible light
Ultraviolet light
Infrared
Radio waves
X-rays
and Gamma rays
