Study Notes
Fluid Pressure
- Pressure (P) is a scalar quantity and is compressive, acting in all directions.
- Pressure in a fluid is directly proportional to the fluid's depth (h) and gravitational acceleration (g).
- Pressure within a fluid is equal at any two points with equal depth, regardless of the container's shape.
- Pressure formula: P = pgh, where p is the fluid's density.
Heat and Temperature
- Heat is a form of energy.
- A unit of heat is joules (J).
- Heat gained is positive (+Q), and heat lost is negative (-Q).
- Temperature is a measure of atomic variation.
