The term radicative forcing has to be explained. Concept introduction: Ø According to IPCC - I nternational P anel on C limate C hange, radicative forcing is the radiactive forcing of the surface – troposphere system due to the perturbation in or the introduction of an agent is the change in net irradiance at the tropopause after allowing for stratospheric tempertures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values. Ø Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors. Ø Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming . Examples: C O 2 , C H 4 .. Ø Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.

Interpretation Introduction

Interpretation:

The term radicative forcing has to be explained.

Concept introduction:

Ø According to IPCC- International Panel on Climate Change, radicative forcing is the radiactive forcing of the surface – troposphere system due to the perturbation in or the introduction of an agent is the change in net irradiance at the tropopause after allowing for stratospheric tempertures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values.

Ø Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors.

Ø Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.

Examples: CO2,CH4..

Ø Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
