A0.0545 kg chunk of an unknown metal that has been in boiling water for several minutes is quickly dropped into an insulating styrofoamtm beaker that contains 0.198 kg of water at room temperature (20.0 ∘c). after waiting for a few minutes, you observe that the water's temperature has reached a constant value of 22.0 ∘c

part a- assuming that the styrofoamtm absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal? in joules per kilogram-kelvin

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

scientific laws are the result of testing theories and proving them to be facts.
