According to the second law of thermodynamics, for a process occurring at equilibrium, the total entropy change of the universe (system plus surroundings) is zero. This implies that the total entropy remains constant, as there is no net driving force for further change in the system.

Which type of system only allows energy exchange with its surroundings?
A closed system is one where only energy, not matter, can be exchanged with the surroundings. This distinguishes it from an open system, which allows both energy and matter to flow, and an isolated system, which allows no exchange of energy or matter.
423
What material is the anode typically made of in alkaline batteries?
In alkaline batteries, the anode is usually made of zinc (Zn) due to its high reactivity with the alkaline electrolyte, allowing for efficient energy transfer and generation of electricity.

What substance is commonly used in cancer therapy?
Cobalt-60 is a radioactive isotope used in cancer therapy due to its high energy radiation, which helps in destroying cancer cells. This makes it an essential substance in the treatment of various types of cancer.

The Earth absorbs radiation in the visible range but emits radiation at the same rate in the form of:
The Earth absorbs solar radiation in the visible spectrum and then emits radiation at the same rate, but in a longer wavelength range, known as infrared radiation. This process is a fundamental aspect of Earth's energy balance and is essential for regulating global temperatures.

Which type of system exchanges both matter and energy with its environment?
An open system can exchange both matter and energy with its surroundings, allowing for continuous interactions and changes. This is in contrast to closed and isolated systems, which only exchange energy or neither matter nor energy, respectively.
