What is Pressure &Temperature
Answers
Explanation:
PRESSURE AND TEMPERATURE RELATIONSHIP. In a closed system where volume is held constant, there is a direct relationship between Pressure and Temperature. ... For example, when the pressure increases then the temperature also increases. When the pressure decreases, then the temperature decreases.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. ... Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as 1⁄760 of this.
Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter. Temperature is measured with a thermometer.
