Questions and model answers on 1.9 Pressure for the CIE IGCSE Physics syllabus, written by the Physics experts at Save My Exams.
Have you ever wondered why our knives need to be so sharp or why the nails we use the end with a sharp point? The answers to all these questions lie in the concept of pressure. It is the ratio of the force applied to the surface area over which the force is applied. We can define pressure as:
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of all of the partial pressures of the component gases. Dalton's law can be expressed with the following equation: Ptotal = P1 +P2 +P3 + ⋯. The figure below shows two gases that are in separate, equal-sized containers at the same ...

The vapour pressure of pure benzene at Certain temperature is 0.850 bar. When a non-volatile Solid of weight 0.5 g added to 39 g of benzene the vapour pressure of Sol becomes 0.845 bar. Find molecular mass of solid structure.
As a result, males and females experience different selective pressures, which can often lead to the evolution of phenotypic differences, or sexual dimorphisms, between the two.
