Initially, 0.05kg of air is contained in a piston cylinder device at 200 oc and 1.6 mpa. the air then expands at constant temper
ature to a pressure of 0.4 mpa. assume the process occurs slowly enough that the acceleration of the piston can be neglected. the ambient pressure is 101.35kpa. (i) determine the work (kj) performed bt the air in the cylinder on the piston. (ii) determine the work (kj) performed by the piston on the ambient environment. neglect the cross-sectional area of the connecting rod. (iii) determine the work transfer (kj) from the piston to the connecting rod. neglect friction between the piston and cylinder. assume that no heat transfer to or from the piston occurs and that the energy of the piston does not change solution
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

it is a vector as it has a magnitude and a direction. If it was a scalar quantity it would just have a magnitude and would be 45 m. Acceleration is an example of a vector quantity
