Nombra 1 (un) producto tecnológico construido con los siguientes materiales : metal, madera o plástico mencionando sus
principales propiedades.
Ejemplo: los cables de los electrodomésticos en su interior son de cobre que es un metal y su
propiedad es que conduce la electricidad. La pava es de metal (Acero inoxidable o aluminio)
porque conduce o trasmite el calor por medio del fuego de la hornalla, su manija es de plástico
que es un aislante, se utiliza ese material para que uno no se queme la mano.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the dissolution of polymer can be thermodynamically described in 2 steps.

i think its 5049.

i hope this !
