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 else can I help you with?
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 does the viscosity vs temperature graph show?
The viscosity vs temperature graph shows how the viscosity of a substance changes as the temperature changes. It typically shows that viscosity decreases as temperature increases.
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 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 boiling point graph reveal about the relationship between temperature and state change in a substance?
The boiling point graph shows that as temperature increases, a substance changes from a solid to a liquid, and then to a gas. The graph reveals the specific temperature at which this phase change occurs, known as the boiling point.
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 is heating curve?
A cooling curve is a diagram or graph that provides a pictorial representation of the change of state or phase of a substance as it cools. It's a plot of temperature vs. time, and it allows an "overview" of the process it was drawn to illustrate. A link can be found below for more information.
What is the graph of a relationship between the physical state of a substance and the temperature and pressure of the substance?
Phase diagram?
What does the viscosity vs temperature graph show?
The viscosity vs temperature graph shows how the viscosity of a substance changes as the temperature changes. It typically shows that viscosity decreases as temperature increases.
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.
A steep slope on a phase change graph indicates?
A steep slope on a phase change graph indicates a rapid change in temperature with respect to the amount of heat added or removed from a substance. During a phase change, such as melting or boiling, the temperature remains constant while the substance transitions between states of matter. The steep slope represents the energy required to overcome the intermolecular forces holding the particles together in a particular state.
In a graph showing temperature change of a material over time temperature change is the .?
dependent variable
What does a shallow slope say on a phase change graph?
A shallow slope on a phase change graph indicates that a relatively small amount of heat is required to change the temperature of the substance during a phase change, such as melting or boiling. This typically occurs when the substance is undergoing a phase transition, where energy is being used to overcome intermolecular forces rather than increasing temperature. Consequently, the shallow slope reflects a higher specific heat capacity during the phase change.
