Models in science help you get the idea of what something looks like that's why your teacher may ask you to draw a diagram to help you remember what the object looks like.
Hope this helps.
There is 213 units i believe hope so
The melting point of pure lead : 327 °C
<h3>Further explanation</h3>
Given
Amount of tin and melting point of solder
Required
The melting point
Solution
The composition of solder = tin and lead
So if it is 100% tin, 0% lead or 0% tin, 100% lead
From the table it is shown that when the position is 100% tin in the solder, the melting point of the solder is 232 °C, so it shows that the melting point of pure lead is obtained when% tin in solder = 0 (100% lead in solder), so that the melting point is obtained. : 327 °C
I think of my backyard. There's tons and tons of flowers back there that attracts many bees during the spring and summer. The bee and the flower have a mutualistic relationship, and here's how: the bee goes from flower to flower, getting pollen, which benefits them. Some of this pollen gets on their bodies, and when they go to another flower, said pollen can rub off on other flowers, giving those flowers pollen. I hope this makes sense!
