respected sir,
I have a question regarding gas law, As we know that In colder regions where density is high but the temperature is low both are inversely proportional to each other, A little confusion when we start gaining altitude the temperature drops, Density drops and pressure drops.... WHY?

We have q1,q2 and q3 with loads of 8uC, 10uC, and -13uC, respectively , available as shown in attached picture . Find the magnitud and the direction of the final force of q1 and q2 over q3
Three liquids are at temperatures of 9 ◦C, 20◦C, and 32◦C, respectively. Equal masses of the first two liquids are mixed, and the equilibrium temperature is 11◦C. Equal masses of the second and third are then mixed, and the equilibrium temperature is 28.3 ◦C. Find the equilibrium temperature when equal masses of the first and third are mixed. Answer in units of ◦C.
