A buret is a device designed to precisely dispense liquids. The scale is calibrated in mL with the zero point at the top with numbers increasing down the buret. Assuming the buret was filled to 0.00 mL, determine the liquid volume dispensed by reading the buret pictured below, taking care to record the proper number of significant figures consistent with the design of the buret.

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.
