Answer these questions :
(a) Which different forms of energy are released when fireworks explode? Why?
(b) Why is it now necessary to use fuels with thrift?
(a) Different forms of energy are released when fireworks explode. These energies are sound energy, light energy, and heat energy. In fireworks explosion, chemical energy is converted into sound energy, light energy and heat energy. these energies dissipate in the surrounding, in form of light, sound, heat and so on.
one can also say that a bigger substance disintegrate into smaller fragments, and going by the principle of conservation of liner momentum, the momentum of fragments can be obtain.

pi=pf
mu=m1u1+m2u2+m3u3+....
(b) Rate of consumption of fuel is larger than its reproduction. So, fuels are limited resources. Hence, we need to use them carefully not wastefully.
