Premium Water Fluid dynamics Pressure
Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

College Pressure Students all over the world are facing different kinds of difficulties while their studies at university. Reasons for that can be very different from student to student. For example‚ pressure from parents‚ problems with financial situation or doing homework etc. For some students college pressure is too high and even unbearable sometimes. Parental pressure is an actual topic for students in all countries all over the world. For the centuries‚ parents are always trying to do good

1802 - Gay-Lussac first formulated the law‚ Gay-Lussac’s Law‚ stating that if the mass and pressure of a gas are held constant then gas volume increases linearly as the temperature rises. This is sometimes written as V = k T‚ where k is a constant dependent on the type‚ mass‚ and pressure of the gas and T is temperature on an absolute scale. (In terms of the ideal gas law‚ k = n R / P.) ▪ 1804 - He and Jean-Baptiste Biot made a hot-air balloon ascent to a height of 6.4 kilometres in an early investigation
