The amount of heat (Q) added into a mass m to change its temperature an amount Delta T is givern m x C (Delta T) and C is called e specific heat depends on mater units us a. True alse 19. The volume per unit mass of a liquid is called specific volume. a. True

Explanation / Answer

14. True as turbulent flow is random flow and cross each others.

15. True as any property divided by mass becomes specific property.

16. True as heat provides kinetic energy to the gas particles and these particles than collide with each other in random fashion.

17. Conduction, as in conduction the heat flows through the substance via molecular transfer of heat.

18. True , specfic heats depends on the material .
