Let&#8217;s consider 3 vessels with a weightless piston sliding without friction, in which there are, respectively: 2 g of hydrogen (H2 ), 18 g of water vapor ( H2O), and 44 g of carbon dioxide (CO2 ) under the same initial conditions, that is, they have: the same [&#8230;]]]></description>

		<description><![CDATA[     Given that the trajectory of a material point (MP) motion is a straight line, the motion is called “a rectilinear motion”. The rectilinear motion can be described by the one-dimensional coordinate system. Let us suppose that at time s MP was at the beginning of motion, at time s MP was at the point with coordinate [&#8230;]]]></description>

		<description><![CDATA[       The law of conservation of mechanical energy for liquids and gases is a special kind formulated by Bernoulli. Let’s consider the conclusion of the law on the example of an ideal incompressible fluid. The ideal liquid is such liquid in which the internal friction can be ignored,  the incompressible liquid  is a liquid whose density is independent [&#8230;]]]></description>

		<description><![CDATA[   Energy is one of the concepts in physics, for which there exists no definition, i.e., undefined concept. We can feel the energy released in the form of heat when a conductor passes a current, we can estimate the reserve of the potential energy of the ball above the Earth&#8217;s surface according to the magnitude [&#8230;]]]></description>
