Document Summary
Convection: heat energy is transported by motions of a fluid generated when a fluid in a gravitational field is heated from below and overturns as cold fluid from above sinks and warm fluid below rises. Latent heat: heat energy released or absorbed during the transition from one phase to another. Latent heat of vaporization: energy is taken up by evaporation and then released to the atmosphere during condensation: (cid:1008)(cid:1009)% of i(cid:374)(cid:272)o(cid:373)i(cid:374)g su(cid:374)light is a(cid:271)so(cid:396)(cid:271)ed (cid:271)(cid:455) ea(cid:396)th"s su(cid:396)fa(cid:272)e a(cid:374)d re-radiated as ir radiation. R = gas constant = 8. 314 jk-1mol-1. N = number of moles of gas. = kg/m3 cold air is denser than warm air. Positive: air parcel is less dense than the surrounding air, so it rises. Negative: air parcel is denser than the surrounding air, so it sinks (subsides) Neutral: air parcel is the same density, so it remains in place. Air moves from high to low pressure zones.
