A sample of unknown pressure occupies 0.776L at a temperature of 298K. The sample of gas is then tested under known conditions and has a pressure of 32.6 kPa and occupies 0.664L at 303K. What was the original pressure of the gas?
A. 27.43 kPa
B. 38.62 kPa
C. 58.73 kPa
D. 84.11 kPa

It can be classified based on its

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
