When 25 mL of 1.0M H2SO4 is added to 50 mL of 1.0 M NaOH at 25oC in a calorimeter, the temperature of the aqueous solution increases to 33.9 oC. Assuming that the specific heat of the solution is 4.18 J/g°C, that its density is 1.00 /mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate the amount of heat absorbed for the reaction

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

Energy transformations that involve one transformation from one type of energy to another are called transformations.
