difference between conduction convection and radiation

1.	difference between conduction convection and radiation
Answer» Reflectance - The ratio of amount of thermal energy reflected by a body in a certain time to total amount of thermal enery falling upon the body in the same time R = r/QAbsorbtance - The ratio of the amount of thermal energy absorbed by a body in a certain time to the total time of the thermal energy incident upon the body in same timea = A/QTransmittance - The ratio of the amount of thermal energy transmitted by a body in a certain time to the total amount of thermal radiation incident on its in the same timet = T/Q
