The various contributions involved till the chapati is made is given below.

<h3>What is food?</h3>

The substance that we intake for the body to charge up by giving nutrients is called the food.

Wheat is a staple food. We make chapati from flour obtained from the wheat grains.

The various contributions involved till the chapati is made is given below.

                 Take required amount of atta in a container

                                                     ↓

                    Add water accordingly to form a dough

                                                     ↓

                 Apply oil to make dough smooth for long time

                                                    ↓

        Take small dough, make it a ball shaped and apply dry flour

                                                    ↓

               Roll it using rolling pin on the chapati maker plate

                                                    ↓

      After making it circular or any shape you want, place it on hot tawa

                                                    ↓

                               Bake it on both the sides

                                                   ↓

                                      Chapati is ready

Thus, the flow chart is made.

Match the following:
joja [24]

Explanation:

1. study of conversion of heat to mechanics → thermodynamics

A branch of physical science which deals with heat and other forms of energy.

2. The Law of Conservation of Energy  → first Law of Thermodynamics

Energy cannot be created nor be destroyed. According to first law of thermodynamics total energy of the system is always constant.

3. Result of applied energy  → work

Work is the way of system to release its energy.

4. Principle that states that in any energy transformation some energy is dissipated as heat  → Second Law of Thermodynamics

5. energy of motion  → kinetic energy

Kinetic energy is defined as energy possessed by the body due to its motion.

6. work/displacement  → force

Work is product of force and displacement.

Work=Force \times displacement

Force=\frac{Work}{displacement}

7. power · time  → energy

Power is defined energy per unit time.

Power=\frac{Energy}{Time}

Energy=Power\times Time

8. Device that transforms heat energy into mechanical energy →  heat engine

heat engine is a device which converts the heat energy which is released due to combustion of fuel into a useful work that is mechanical energy.

9 . Energy due to position  → potential energy

Potential energy is defined as energy possessed by the body due to its position.

10. efficiency of a heat engine unit of heat  → calorie

11. Measure of molecular motion  → Temperature

Kinetic energy is directly proportional to temperature.

Greater the motion more will be the kinetic energy and with more will be the temperature.

12. Heat given off by a liquid with no change in temperature  → latent heat of fusion

Latent heat of fusion is defined as heat released by 1 mole of substance when it under goes phase change that is from solid to liquid.

13. Motion within solids  → vibrational motion

Vibrational motion is the motion in which particle oscillates from its mean position.

14. Phase of matter on the sun → plasma

Plasma is hot ionized gas with equal number of positive and negative ions. Due to high temperature of sun most the gas are in the plasma state.
