Why does a soild change to liquid when heat is added?

Masja [62]

Answer:

Explanation:

solid is particles packed up together like a family.

liquid is made out of particles as well but the are a little spaced out like a bunch of friends going home after a busy school day.

A solid changes state because when heat is applied it states changing state into a liquid.

like you freeze an ice cube and when it out on a summer day in a drink it starts melting AKA (A SOLID + HEAT =A LIQUID

A SPARK PLUG IN AN AUTOMOBILE ENGINE CONSISTS OF TWO

kirill [66]

Answer:

Electric potential, $V=3.52\times 10^{12}\ volts$

Explanation:

It is given that,

The magnitude of electric field, $E=4.7\times 10^7\ V/m$

Distance between automobile engines that consists of metal conductors, $d = 0.75\ mm = 7.5\times 10^4\ m$

Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:

$V=E\times d$

$V=4.7\times 10^7\ V/m \times 7.5\times 10^4\ m$

$V=3.52\times 10^{12}\ volts$

So, the magnitude of the potential difference between the conductors is $3.52\times 10^{12}\ volts$ . Hence, this is the required solution.
