10. (14 points) The pressure of a certain quantity of gas is given by p = ", where n is the quantity (in moles), R is a constant, T is the temperature (in Kelvins) and V is its volume (in cubic metres). The pressure is in pascals. A scientist is conducting an experiment in which she let the volume of the gas container increase at a rate of 0.05 cubic metres per second while maintaining a constant temperature, and without changing the amount of gas. How fast is the pressure changing when the pressure is 100, 000 pascals and the volume is 2 cubic metres? Show all your work
