Based on a scene showing a physical change in a piston-cylinder assembly, the thermodynamic numbers indicated below are 760 torr 760.
<h3>What elements make up the first rule of thermodynamics?</h3>
The first law of thermodynamics states that the following equation describes how the change in internal energy relates to the heat exchanged by the system and the work performed on or by the system: U = Q + W, where Q represents the heat energy that the system exchanged.
<h3>What are the thermodynamic quantities' two components?</h3>
Extensive and intensive thermodynamic quantities are traditionally separated into these two categories. While intensive quantities are independent of system size, extensive quantities grow linearly with system size.

<u>Answer:</u>
<em>B. A and B</em>
<em></em>
<u>Explanation:</u>
1. Solids have a definite volume, definite size and definite shape
2. The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.
3. Melting point is the temperature at which solid changes into a liquid.
4. When a solid is heated to the melting point the intermolecular forces are overcome by the energy and the molecules present in it moves from its fixed position to take its liquid state which is called as melting.
Molar mass of salt = 58.44 grams/mole
Answer:
Astrology
Explanation:
One characteristic of science is that it must be reproducible. Other scientists must be able to repeat the original experiments and get the same result. That's what makes scientific claims reliable.
Astrology contends that the positions and motions of stars and planets can affect people and events on Earth. This has been disproved, so astrology is a pseudoscience
.
Biology, chemistry, and physics are sciences.
