Question

I don't understand why six, seven and nine are false?

6. A high specific heat indicates that little energy is needed to change the temperature of the substance in question. The energy needed to break bonds in hydrocarbon combustion is higher than the energy needed to form the bonds in the products. 8. Work is a product of force and distance. 9. A coiled snake is an example of kinetic energy.

Answer 1

6. Specific heat capacity is heat required to increase temperature of One gram substance by 1°C.

So higher specific heat means more amount of energy will be required to raise temperature by 1°C. But given statement says exactly opposite, which is wrong.

7. Since Hydrocarbon Combustion reaction always realses energy, so overall energy required to break bonds must be lesser than energy released during bond formation. Which given statements isn't justify, wrong statement.

9.Since Kinetic energy is related to motion of a object. Here coiled snake is mentioned which means it's not moving so it will not be having any kinetic energy. Wrong statement.
