Study Notes
Units of Measurement
- The unit used to measure area is not specified, but common units include square meters (m²), square centimeters (cm²), and square inches (in²).
- The unit of force is the Newton (N).
- The unit of pressure is the Pascal (Pa), which is equivalent to one Newton per square meter (N/m²).
Pressure and Force
- When the force increases, the pressure also increases.
- When the surface area is increased, the pressure decreases.
True or False Statements
- FALSE: The unit of force is not N/cm², it's just N.
- TRUE: Gas pressure is caused when gas particles hit the walls of their container.
- TRUE: The pressure in a tyre or balloon goes up when more air is pumped in.
- FALSE: The amount of gas in the container does affect the pressure of a gas.
- FALSE: Higher temperature leads to higher pressure in a gas, not lower pressure.
