Pressure units are used to measure the force exerted on a surface per unit area.

• Pressure is typically measured in units such as pascal (Pa), bar, psi, or atmosphere (atm).

• 1 pascal (Pa) is equal to 1 newton per square meter (N/m²).

• 1 bar is approximately equal to atmospheric pressure at sea level (1 atm).

• 1 psi (pound per square inch) is equal to approximately 6895 pascals (Pa).

The fire triangle is a model that explains the three elements required for a fire to start and continue. Diamonds are a form of carbon that is highly valued for their beauty and durability.

• The fire triangle consists of three elements: fuel, heat, and oxygen.

• If any of these elements are removed, the fire will be extinguished.

• Diamonds are formed deep within the Earth's mantle and are brought to the surface through volcan...read more
