Mechanical Engineering

Indicate whether the following statements are true orfalse. Explain.
Rate of energy transfer induced as a result of a temperaturedifference between a system and its surroundings is called apower.
When a system undergoes a process, the terms work and heat arerefer to what is being transferred.
If an object of known mass and initially at rest falls from aspecified elevation, then hits the ground and comes to rest at zeroelevation. It means its kinetic energy is converted to potentialenergy.
The three modes of energy storage for individual atoms andmolecules making up the matter within a system are kinetic,potential, and internal energies.
For any cycle, the net amounts of energy transfer by heat andwork are equal.
Current passes through an electrical resistor inside a tank ofgas. The energy transfer can be considered work.
The internal energy of a system at a state hassignificance.
In the case of refrigeration, its coefficient of performance isalways greater or less than one.
Is it correct to say that a system contains heat?
Adiabatic process involving no heat transfer by energy.
