What do the lines on a phase diagram represent?
The lines on a phase diagram represent the boundaries between the different phases of a substance (such as solid, liquid, and gas). These lines show the conditions of temperature and pressure at which two phases can exist in equilibrium with each other.
What happens after dipping a substance into a pH solution?
When a substance is dipped into a pH solution, it will either change color due to a chemical reaction with the solution, or it may not show any visible change if the substance is neutral. This process helps determine the acidity or basicity of the substance based on the pH solution's color change.
Which graph best represents a change of phase from a gas to a solid?
The graph that best represents a change of phase from a gas to a solid would show a decrease in temperature over time as the gas loses energy and transitions into a solid state. The temperature remains constant during the phase change itself due to the energy being used to break intermolecular bonds rather than increase temperature.
How can the term cooling curve be explained?
The term cooling curve can best be explained by a graph which represents the state of a gas to a solid or to a liquid. You can find many explanations and demonstrations of experiments that show this on websites including Youtube and kentchemistry.
What is a change in the form but not nature of a substance bonds are not broken?
A physical change involves altering the form of a substance, such as changing its shape or state, without breaking the chemical bonds that hold its molecules together. This type of change is reversible and does not result in the formation of a new substance.
A graph that shows the change in the temperature of a substance as it is heated will show?
A graph showing the change in temperature of a substance as it is heated will typically show an initial increase in temperature as heat is added, followed by a plateau where the substance changes phase (e.g., from solid to liquid), and then another increase in temperature. The specific shape of the graph will depend on the properties of the substance being heated.
What will a graph show if the change in temperature of a substance is heated?
A graph of the change in temperature of a substance as it is heated will typically show an initial increase in temperature until a plateau is reached, known as the phase transition or melting point. After this, the temperature will continue to rise again as the substance transitions to a gas.
What type of graph is used to show change?
bar graph
The type of graph used to show continuous change?
A line graph.
What is a graph that uses line segments to show how data change?
line graph
What does line graph show?
Line graphs show the relationship between the change in one variable to the change in another. (change) On a computer, a line graph shows lots of pixels.
Does a line graph show the change at one point in time?
A line graph shows change over time.
What happened to the solid substance in the energy box as most heat was added. Describe what activity in the molecules and the shape of the graph?
As more heat was added, the solid substance melted into a liquid and then evaporated into a gas. The molecules in the substance gained energy, vibrated more vigorously, and eventually overcame the intermolecular forces holding them together as a solid. The graph would show an initial increase in temperature as the solid heated up, followed by a plateau during the phase change from solid to liquid, and then another increase as the liquid turned into a gas.
What is the best graph to show temperature change?
Scatter graph i think. Hope that helps!
What is the type of graph that is useful for showing trends or continuous change?
A line graph is useful for showing trends or continuous change. Other kinds of graph also will show these, but a line graph is usually clearest.
What type of graph would be most appropriate to show the change in temperature over the course of a day?
A line graph
How do you know when to use a pie graph or not?
if your trying to show percentage and not change in percentage u use a pie graph
