1 answer

Here’s what each of the mentioned variables measures along with their respective units:

  1. Temperature:

    • Measures: The average kinetic energy of the particles in a substance, reflecting how hot or cold the substance is.
    • Units: Kelvin (K), Celsius (°C), Fahrenheit (°F)

  2. Pressure:

    • Measures: The force exerted per unit area, indicating how much force is applied to a surface for a given area.
    • Units: Pascal (Pa), atmospheres (atm), millimeters of mercury (mmHg), pounds per square inch (psi)

  3. Volume:

    • Measures: The amount of three-dimensional space occupied by a substance.
    • Units: Cubic meters (m³), liters (L), milliliters (mL), gallons (gal)

These measurements are fundamental in various scientific disciplines, including physics, chemistry, and engineering.
