EVERYDAY SCIENCE

Detailed explanation-1: -A closed system does not allow matter to enter or leave, but does allow energy to enter or leave. A covered pot on the stove is approximately a closed system. An isolated system does not allow either matter or energy to enter or leave. A thermos or cooler is approximately an isolated system.

Detailed explanation-2: -A closed system can exchange energy with its surroundings through heat and work transfer. In other words, work and heat are the forms that energy can be transferred across the system boundary.

Detailed explanation-3: -The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant-it can neither increase nor decrease without interference from outside.

Detailed explanation-4: -The law of conservation of energy is an important law of physics. Basically, it says that while energy can turn from one kind into another, the total amount of energy doesn’t change. This law applies only to closed systems, meaning systems that can’t exchange energy with their environment.
