Which of the processes is exothermic? a) evaporation of alcohol
b) sublimation of iodine
c) solidification of volcanic lava
d) burning of paper

Choice C as my opinion

Explanation:

solidification of volcanic lava has to do with changes in earth and the thermal structure that's just a point not sure though

hope I was helpful though thank you

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

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