Answer:
Lead
Step-by-step explanation:
According to the chart, we can see that lead has the highest number here, so lead has the highest freezing / melting point in this chart.
If we were looking for the element with the lowest freezing / melting point, then we would look for the lowest number, which would belong to Helium, at -272.
With mass, it would be measured in grams. The only way to measure mass is with a triple beam balance, which uses grams.
Answer:
2A/h - b<em>2</em>= b<em>1</em>
Step-by-step explanation:
A = 1/2 ( b<em>1</em>+ b<em>2</em>) h
Multiply each side by 2
2*A = 2*1/2 ( b<em>1</em>+ b<em>2</em>) h
2A = ( b<em>1</em>+ b<em>2</em>) h
Divide each side by h
2A/h = ( b<em>1</em>+ b<em>2</em>) h/h
2A/h = ( b<em>1</em>+ b<em>2</em>)
Subtract b<em>2 </em>from each side
2A/h - b<em>2</em>= b<em>1</em>+ b<em>2-</em>b<em>2</em>
2A/h - b<em>2</em>= b<em>1</em>
