Sum of kinetic, potential, flow, and internal energies.
Sum of all microscopic forms of energy in a system.
Kinetic energy is due to motion, while potential energy is due to position.
It consists solely of kinetic, potential, flow, and internal energies.
KE = 1/2 mv².
PE = mgz.
Energy required to push an element across a boundary.
It states that energy cannot be created or destroyed, only transformed.
Closed systems do not exchange matter, while open systems do.
No net change in the properties of a system over time.
It introduces the concept of entropy and the direction of energy transfer.
An idealized thermodynamic cycle that provides maximum efficiency.
It measures a material's ability to emit energy as thermal radiation.
Conduction transfers heat through materials, while convection involves fluid movement.
It describes heat conduction through a material.
It relates the rate of heat loss of a body to the temperature difference with its surroundings.
Measured in Watts (W), equivalent to Joules per second (J/s).
Amount of heat needed to raise 1 kg of a substance by 1 K.
Constant volume applies when pressure varies; constant pressure applies when volume changes.
Energy is absorbed or released without a temperature change.
Energy required to change a substance's phase, measured in kJ/kg.
They are equal in a closed system.
Expressed in W/m², indicating heat transfer per unit area.
Energy cannot be created or destroyed; it can only change forms.
Kelvin is the absolute temperature scale, essential for thermodynamic equations.
Heat In equals Heat Out when no reactions occur.
