An ideal gas, initially at a volume of 2 L and pressure of 7 kPa, undergoes isothermal expansion until its volume is 7 L and its pressure is 2 kPa. Calculate the work done by the gas during this process. Answer in units of kJ. PART TWO:Find the heat added to the gas during this process. Answer in units of kJ

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
