The graph shows the variation of pressure with volume for a fixed amount of gas. Two curves are shown:
State the relationship between pressure and volume for a fixed mass of gas at constant temperature.
Using the graph, outline how pressure changes with increasing volume for both curves.
Explain how the graph indicates that the solid curve corresponds to a higher temperature.
Determine the pressure when the volume is for both curves.
A sealed container holds a fixed mass of gas at constant temperature. The volume of the gas is reduced from to .
State the gas law that applies to this situation.
If the initial pressure is , calculate the final pressure.
Explain why the pressure increases as the volume decreases.
Which statement is true about the resistance of a filament lamp as it operates at higher voltage?
A student connects a variable resistor to a battery of emf and measures the current in the circuit as the resistance is adjusted. The internal resistance of the battery is negligible.
State Ohm’s law.
The current in the circuit is when the resistance is adjusted to a certain value. Calculate this resistance.
The student increases the resistance. Describe and explain what happens to the current and the power dissipated in the resistor.
An ideal gas is confined in a container with a movable piston at a temperature of . If the volume of the gas is doubled while the pressure remains constant, what will be the final temperature of the gas in degrees Celsius ()?
