-- We know what the weather will be like in your town tomorrow.
-- We know the distance from us to the Sun and the Moon.
-- Best of all: Your doctor can give you shots so you won't get flu,
chicken pox, measles, mumps, whooping cough, tetanus, diphtheria,
smallpox, or polio.
Almost EVERY kid used to get chicken pox, measles, and mumps
when I was in school, and thousands of kids used to die every year
from diphtheria and polio. And now, you probably never heard of
most of these.
melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.
endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.
in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
