<span>The type of graph that’s most useful for showing how one variable changes in response to another variable is called a line graph. A line graph is used when you have one independent and one dependent variable. Usually, the independent variable is assigned to the x-axis, while the dependent variable is assigned to the y-axis.</span>

Answer:
Chemical change
Explanation: Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
Answer:
![C_{Fe}=0.096 \frac{cal}{g*C}](https://tex.z-dn.net/?f=C_%7BFe%7D%3D0.096%20%5Cfrac%7Bcal%7D%7Bg%2AC%7D)
Explanation:
The energy gained by the water:
![E=\Delta T*C*V* \rho](https://tex.z-dn.net/?f=E%3D%5CDelta%20T%2AC%2AV%2A%20%5Crho)
![E=(33.2 - 20)C*\frac{1 cal}{g*C}*35 mL*1 g/mL](https://tex.z-dn.net/?f=E%3D%2833.2%20-%2020%29C%2A%5Cfrac%7B1%20cal%7D%7Bg%2AC%7D%2A35%20mL%2A1%20g%2FmL)
![E=462 cal](https://tex.z-dn.net/?f=E%3D462%20cal)
This energy is equal to the energy lost by the iron:
![E=\Delta T*C_{Fe}*m_{Fe}](https://tex.z-dn.net/?f=E%3D%5CDelta%20T%2AC_%7BFe%7D%2Am_%7BFe%7D)
In equlibrium the T of the iron and the water are the same
<em>(the negative sign is because the iron loses the energy)</em>
![C_{Fe}=0.096 \frac{cal}{g*C}](https://tex.z-dn.net/?f=C_%7BFe%7D%3D0.096%20%5Cfrac%7Bcal%7D%7Bg%2AC%7D)
