The function of the state of a thermodynamic system whose change in any differential reversible process is equal to the heat absorbed by the system from its surroundings divided by the absolute temperature of the system.

What is entropy?

100

The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.

200

A law that states if two systems are separately found to be in thermal equilibrium with a third system, the first two systems are in thermal equilibrium with each other; that is, all three systems are at the same temperature.

What is Zeroth?

200

A structure or body that is over-constrained, such that there are more unknown supports than there are equations of static equilibrium.

What is statically indeterminate?

Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.

What is convection?

400

The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.
