When the ice is heated, the temperature _______ until the temperature becomes _________ . The temperature at which this occurs is called the ________ point.
(a)
Which chart correctly shows a cooling curve for a gas that becomes a solid?
Substance A has a melting point of 98°C.
Substance B has a melting point of 801°C.
Both solids are heated until they become liquids and their heating curves are compared.
Which statement is true?
The horizontal portion of the heating curve for substance B will be much higher than substance A.
Both substances will have the same heating curves, as they are both solids changing state into liquids.
The horizontal portion of the heating curve will be much longer for substance A compared to substance B.
Both substances will increase their temperature at the same rate, as they are both solids.

Matter can be classified by analyzing its composition as it is shown in the diagram. Steel is a material that contains two elements: iron (Fe) and carbon (C). Two different samples of steel have different quantities of these two elements, but both have uniform composition. Using the diagram above, how would you classify steel?
As pure substance, because it has uniform composition and it is a compound
As a heterogeneous mixture, because is formed by two different elements
As a homogeneous mixture, because is formed by two different elements and it is uniform
As pure substance, because different samples have different composition
