A gas initially at 2.8 bar and 60°C is compressed in a cylinder-piston assembly to a final pressure of 14 bar in an isothermal internally reversible process. Determine the work and heat transfer, each in kJ per kg of gas, if the gas is (a) Refrigerant 134a, (b) air as an ideal gas. Sketch the process on p–v and T–s coordinates.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the rearrangement of particles in a physical change. hope this
