A 1.23-g sample of a salt is added to 105.0 g of water in a coffee cup calorimeter. If the temperature increases by 2.50 °C, what is the approximate amount of heat (in kJ) involved in the dissolution of the salt, assuming the specific heat of the resulting solution is 4.18 J/g °C​

it's filtration, but this is an assumption so my apologies if i got this

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
