Plumbers often use a "dielectric union" joint to join pipes of different types. For example, copper pipes in a house might need to be joined with lead pipes in the main water supply. The dielectric union is a plastic joint that will not conduct electricity. Propose an explanation for why a copper pipe can't simply be welded directly to a lead pipe.

Respuesta :

Answer:

a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.

Explanation:

A lead pipe is a pipe that's made of lead and is usually used in distribution of potable water to connect a water main source to a user's preferred area.

Now, a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.

Lead has a melting point of 327.5° C while copper wire has a melting point of 1082.778 °C
