∙ 7y ago
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 does the flat portion of the temperature time graph indicates?
The flat portion of a temperature-time graph indicates a phase change where the substance is either melting or boiling. During these phase transitions, the temperature remains constant as the substance absorbs energy to change its state rather than increase in temperature.
What A steep slope on a phase-change graph indicates?
Different
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 will happen to happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When thermal energy is added to a substance, its atomic or molecular activity will increase, leading to higher kinetic energy and greater movement of particles. This can cause the substance to change state, such as melting from a solid to a liquid. The shape of the graph representing temperature changes may show plateaus where phase transitions occur before the temperature starts to rise again.
What is a graph that shows the different states of a substance according to the temperature and pressure it is under?
A phase diagram is a graph that shows the different states of a substance (solid, liquid, gas) based on the temperature and pressure it is subjected to. It displays the conditions at which phase transitions occur, such as melting or boiling points.
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 change will show in a graph in temp of an substance a s it is heated will show what?
As a substance is heated, its temperature will increase in a linear manner until it reaches its melting or boiling point, at which point the temperature will remain constant as the substance changes phase. This will appear as a straight line with a plateau on a temperature vs. time graph.
What does the flat portion of the temperature time graph indicates?
The flat portion of a temperature-time graph indicates a phase change where the substance is either melting or boiling. During these phase transitions, the temperature remains constant as the substance absorbs energy to change its state rather than increase in temperature.
What is heating curve?
A heating curve is a graph that shows how the temperature of a substance changes as it is heated over time. It typically shows the phases of matter (solid, liquid, gas) and the transitions between them as heat is applied. Heating curves are used to understand the change in energy within a substance as it undergoes heating.
What A steep slope on a phase-change graph indicates?
Different
What does a flat line on a gas liquid solid graph means what?
A flat line on a phase diagram indicates a phase transition occurring at a constant temperature and pressure. For example, a flat line on a gas-liquid equilibrium graph means that the substance is transitioning between the gas and liquid phases without changing temperature or pressure.
What is the graph of a relationship between the physical state of a substance and the temperature and pressure of the substance?
Phase diagram?
In a graph showing temperature change of a material over time temperature change is the .?
dependent variable
What does the flat portion of the temperature time graph in the experiment of melting point indicates?
The flat portion of the temperature-time graph during the melting point experiment indicates that the substance is undergoing a phase change. As heat is being absorbed to break the intermolecular bonds and transform the solid into a liquid, the temperature remains constant until all of the substance has melted.
What is the best graph to show temperature change?
Scatter graph i think. Hope that helps!
What is a curve showing the relationship between temperature and time for a given amount of liquid heated at a constant rate?
It is a heating curve. It shows the temperature changes over time as a substance is heated continuously at a constant rate, highlighting phase changes and plateaus in temperature where energy is absorbed to overcome intermolecular forces.
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.
