The termthat describes the relationship by the graph is Charles's law
answer
What term describes the relationship illustrated by the graph in fig23?
question
The volume of a gas increases when its temperature increases at constant pressure.
answer
How does the volume of a gas change when it's temperature is increased at constant pressure ?
question
The volume of the gas at the temperature of 400 kelvin (127^c ) will be 75
answer
Suppose the temperature of the gas is increased to 400 kelvins( 127^c). Use the fig 23 to predict the volume of the gas at this temperature.
question
The relationship between the pressure and the volume of gas is that the pressure of a gas varies inversely with its volume at constant temperature
answer
What is the relationship between the pressure and the volume of a gas
question
The gas pressure when the gas volume is 125 ml is 50
answer
Use the graph in figure 25 to estimate the gas pressure when the gas volume is 125 mL.
question
When comparing and contrasting the Charles's law and Boyle's law, Boyle's law is about the relationship between the volume and temperature at constant pressure. Temperature and volume are directly proportional . Boyle's law represents a curved graph while Charles's law represents a straight line graph.
You can tell the difference between a graph in which one variable is directly proportional to another is when a graph of two variables in a straight line pass through the origin
answer
Compare and contrast the Charles's law and Boyle's law graphs. How can you tell the difference between a graph in which one variable is directly proportional to another and a graph in which two variables vary inversely?
