27 de mai. de 2024 · I am studying David Tong's lecture note on statistical physics, and I have a question regarding the precise definition of pressure. I checked other postings in this community, but was unable to get the answer. Also, apologies for this absurdly long question.
13 de mai. de 2024 · pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which it is exerted; i.e., it is one-half pound per square inch.
16 de mai. de 2024 · The vapour pressure of a liquid is represented by the equation log (P/Torr) 1625 + 8.750 т where I is the temperature in Kelvins. (a) calculate the ethalpy of vaporization at P=1117 torr. Views: 5,218 students. Updated on: May 16, 2024.
22 de mai. de 2024 · Pressure is defined as the force acting by an object perpendicularly on a surface on a given per unit area. It is basically the ratio of force acting per unit area.It unit is Pascal (Pa). Pressure may be Gauge pressure, Hydrostatic pressure, Thrust and Fluid pressure. To do a question based on pressure, one should know its various forms and factors affecting pressure. One should have a deep ...
15 de mai. de 2024 · Peer pressure is the process by which members of the same social group influence other members to do things that they may be resistant to, or might not otherwise choose to do. Peers are people who are part of the same social group, so the term "peer pressure" refers to the influence that peers can have on each other.
