The 1st law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• Energy is conserved in any thermodynamic process

• Heat and work are two ways energy can be transferred

• The law applies to closed systems

• An example is a car engine converting chemical energy to mechanical energy

• Another example is a kettle converting electrical energy to heat energy

The 2nd law of thermodynamics states that the total entropy of a closed system always increases over time.

• Entropy always increases in a closed system

• Heat cannot flow from a colder body to a hotter body without external work being done

• Efficiency of a heat engine is limited by the temperature difference between the hot and cold reservoirs

• The law applies to all natural processes and cannot be violated
