An ideal monatomic gas at temperature T is held in a container. If the gas is compressed isothermally, that is at constant temperature, from a volume of Vi to Vf ,
a) What is the change in the (internal) energy of the gas?
b) How much work has been done on c) Has heat been transferred into or out of the gas during the process? If so, how much?
d) Show that the 1st law of thermodynamics is satisfied gas?

Answerinternal combustion engine fuel;

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
