What does a Graph of melting point and freezing point of naphthalene look like?
The graph of the melting point and freezing point of naphthalene would show a plateau at the melting point, as the solid naphthalene transitions into the liquid phase, and a plateau at the freezing point, as the liquid naphthalene transitions back into the solid phase. The melting point and freezing point of naphthalene are the same at approximately 80 degrees Celsius.
Which of these would best show how the average daily temperature rises and falls over the course of a month?
A line graph would be the best way to show how the average daily temperature rises and falls over the course of a month. Each point on the graph would represent the average daily temperature for a particular day, and the line connecting these points would visually show the trend of temperature changes throughout the month.
What type of graph show both temperature and precipitation?
A dual-axis graph can be used to show both temperature (on one axis) and precipitation (on another axis) on the same graph. Alternatively, a line graph can be used with two different lines representing temperature and precipitation over time.
Isotherm in physics?
Isotherms in thermal physics are the lines on a pressure versus volume graph for an ideal gas, where the pressure and volume are alowwed to vary but temperature is kept constant. They are the result of Isothermal expansions or contracions of ideal gasses.
What two kinds of information are shown in a climograph?
temperature and precipitation

How does the temperature of the freezing point of lauric acid compare with the melting point temperature of the same substance as indicated on the graph?
The freezing point of lauric acid is equivalent to its melting point. This means that the temperature at which lauric acid transitions from solid to liquid form is the same as the temperature at which it transitions from liquid to solid form.
Why is the meting and freezing point of a substance the same?
The melting and freezing points of a substance are generally the same because they represent the temperature at which the solid and liquid phases of a substance are in equilibrium. This means that at the melting point, a solid changes to a liquid, while at the freezing point, a liquid changes to a solid.
How can you determine the melting point of a substance based in its heating curve?
Heating curves (temp vs time) show the transition of a solid to a liquid to a gas. The solid begins to absorb heat, which is represented by a gradual increase in your curve starting from the origin. Eventually, the solid will reach the melting point, at which the temperature will cease to increase until it has fully transitioned to a liquid phase. Therefore, the melting point is the y-value correspondind to the first horizontal portion of the heating curve.
How can you use a graph to find freezing point of Stearic acid?
To find the freezing point of stearic acid using a graph, you could plot a cooling curve of temperature versus time as the stearic acid solidifies. The freezing point is the point on the graph where the temperature remains constant as the stearic acid transitions from liquid to solid. By analyzing this plateau in temperature, you can determine the freezing point of stearic acid.
What happens to the temperature of naphthalene during melting?
Lab: Melting / Freezing Point of NaphthaleneObjective: In this lab, you will investigate the melting and freezing point of the substance, naphthalene (moth ball flakes). You will heat solid naphthalene and record temperature changes and examine the graph to determine the melting point of the substance. You will then cool naphthalene and record temperature changes in order to determine the Freezing point of the substance Part A: What happens to temperature as naphthalene melts?Objective: As heat is applied to liquid naphthalene, the temperature rises. As the temperature rises, the naphthalene will eventually start to melt. This lab experiment tries to answer the question: what happens to the temperature of naphthalene as it melts? In this lab, you will heat the liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.Part B: Determining the freezing point of naphthaleneObjective: Freezing point is a characteristic property of matter. As heat is taken away from a liquid, the temperature of that liquid decreases as the substance begins to freeze. This lab experiment tries to answer the question: what is the freezing point of an unknown liquid (naphthalene)? In this lab, you will cool liquid naphthalene, and record the temperature changes. You will graph the temperature changes before drawing any conclusions.
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.
Gold's melting point is 1064 degrees celsius and its boiling point is 2808 degrees celsius use this data to make a bar graph?
A bar graph may not be the most suitable way to represent this data since the boiling point is significantly higher than the melting point, leading to a distortion in the graph. A better alternative could be a simple line graph showing the relationship between temperature and physical state (solid, liquid, gas) of gold at different temperature points.
What if your graph has two flat section joined by slope. What does it mean where the graph is flat On the graph mark when the ice is melting Also mark the boiling water.?
A graph with two flat sections joined by a slope represents a phase change. The flat sections indicate a constant temperature during a phase change, such as when ice is melting or water is boiling. The slope represents a temperature increase or decrease during the transition between phases. In a graph, you would mark the flat section for ice melting and boiling water where the temperature remains constant.
What does the melting point graph reveal about the physical properties of the substance?
The melting point graph shows the temperature at which a substance changes from a solid to a liquid. It reveals the substance's melting point, which is a key physical property that can help identify and characterize the substance.
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.
Why do the temperatures on the graph only gp from 0C to 100C?
The temperature range from 0°C to 100°C corresponds to the freezing and boiling points of water, which are commonly used as reference points on temperature scales. This range covers the typical temperatures that humans encounter in daily life, making it a convenient scale for general purposes like weather forecasting and cooking.
