The Newton's constant appears in the law of gravitation and as the name implies, is a constant. This constant has a definite value of 6.67×10−11 Nm2/kg2. This constant is a part of the formula for the gravitational force of attraction between two or more bodies....

which remain constant irrespective of its state of aggregation, the properties of a material depend on how its subunits are assembled. Some such emergent properties are called “collective,” because they are only found in assembled samples. For example, ferromagnetism is a property not of a singl...
In this step, the cylinder loses heat (Qc) to the cold reservoir. This step is again isothermal, which means that it happens at a constant temperature of Tc. Due to the heat loss, the gas compresses, pushing the piston down. Step 4: Reversible Adiabatic Gas Compression ...
