state the principle of conversation of energy. What are various energy transformations that occur when you are riding a bicycle?

Principle of conservation of energy states that “energy can neither be created nor destroyed,only it can be changed from one form to another".

When we are riding bicycle, our muscular energy gets converted into kinetic energy and heat energy. The kinetic energy results in the movement of bicycle, while heat energy heats the body of the rider.

nikkikeser: give me one more answer please

SWATTIKMUKHOPADHYAY: yes

asif2996: ya sure if i know

asif2996: ques ???

nikkikeser: in a chemical reaction 5.3g of sodium carbonate reacted with 6g of acetic then it was observed that 8.2g of sodium, acetate,0.9g of water and Xg of carbon dioxide were produced what is the value of x?

SWATTIKMUKHOPADHYAY: 11.3- 9.1= 2.2g

nikkikeser: solve it step by step

SWATTIKMUKHOPADHYAY: FROM LAW OF CONSERVATION OF MASS , THE TOTAL MASS OF REACTANTS IS EQUAL TO THE TOTAL MASS OF PRODUCTS. ......SO 5.3+ 6= 8.2+ 0.9+x......x = 2.2

SWATTIKMUKHOPADHYAY: alright?

nikkikeser: yeah

ACCORDING TO THE LAW OF CONSERVATION OF ENERGY, ENERGY CAN NEITHER BE CREATED NOR DESTROYED. IT CAN ONLY BE TRANSFORMED FROM ONE FORM TO ANOTHER AND THE TOTAL ENERGY BEFORE AND AFTER TRANSFORMATION REMAINS CONSTANT OR CONSERVED.

WHILE RIDING A BICYCLE, THE MUSCULAR ENERGY OF THE RIDER GETS CONVERTED TO KINETIC ENERGY AND HEAT ENERGY. THE KINETIC ENERGY RESULTS IN THE MOVEMENT OF THE RIDER ALONG WITH THE CYCLE WHILE THE HEAT ENERGY IS PRODUCED BECAUSE OF OVERCOMING THE FRICTIONAL FORCE AND HEATS THE BODY OF THE RIDER.
