The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• Energy is conserved in a system

• Energy can be transferred between different forms (e.g. heat, work)

• The total energy of a closed system remains constant

• Mathematically expressed as: ΔU = Q - W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system

Net heat is not equal to net work done in most cases, as they represent different forms of energy transfer.

• Net heat is the transfer of thermal energy between systems due to a temperature difference.

• Net work done is the transfer of mechanical energy between systems due to a force acting over a distance.

• In many real-world scenarios, the net heat and net work done are not equal due to inefficiencies and losses.

• For example...read more

Convection is the transfer of heat through a fluid (liquid or gas) by the movement of the fluid itself.

• Convection occurs when a fluid is heated, becomes less dense, and rises, carrying heat with it.

• Cooler fluid then moves in to take its place, creating a continuous cycle of heat transfer.

• Examples include boiling water in a pot and the movement of air in a room heated by a radiator.

Pascal's laws state that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.

• Pressure applied to a confined fluid is transmitted equally in all directions.

• The pressure at any point in a fluid is the same in all directions.

• Examples include hydraulic systems and car brakes that utilize Pascal's laws to function effectively.
