A 100.00 ml of volume of 0.500 m hcl was mixed with 100.00 ml of 0.500 m koh in a constant pressure calorimeter. The initial temperature of individual acid and base was 23.0 oc. The final temperature after mixing was 25.5 oc. The specific heat of the solution was 3.97 j g-1 oc-1 assume the density of the solution is 1.00 g ml-1

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

What are the dimensions of the cross section that passes through the points a, f, g, and d?
