A coin is tossed twice and comes up head both times someone says theres something wrong with the coin. A coin is supposed to come up heads only half the time not every time

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
