What material is primarily responsible for providing tensile strength in reinforced concrete?
What is steel reinforcement (rebar)?
The substance flowing through the wire of the circuit.
What is current?
In a chemical process, what happens to the temperature of a substance when heat is added while its phase is changing, assuming constant pressure?
What is the temperature remains constant during the phase change?
This part of the computer is often called the “brain” because it performs calculations and runs instructions.

What property describes a material’s ability to resist deformation under an applied load?
What is stiffness?
What property of soil describes the ratio of the volume of voids to the total volume of soil?
What is porosity?
The law that indicates relationship between voltage, current, resistant in a circuit. I=V/R.
What is Ohm's Law?
What dimensionless number is commonly used to determine whether fluid flow is laminar or turbulent?
What is the Reynolds number?
This type of loop continues running as long as its condition remains true, common in beginner programming assignments.
What is a while loop?
What thermodynamic law states that energy cannot be created or destroyed, only transferred or transformed?
What is the First Law of Thermodynamics?
Water flows through a pipe that suddenly becomes narrower. Assuming steady incompressible flow, what happens to the fluid velocity?
What is it increases?
A component that has an ideally zero resistant in one direction, but an ideally infinite resistant in the other direction.
What is a diode?
What term describes a substance that increases the rate of a chemical reaction without being consumed by the reaction?
What is a catalyst?
This term describes an error that occurs when a program tries to use a variable that hasn’t been given a value yet.
What is an uninitialized variable?
According to Bernoulli’s equation, if the velocity of an incompressible fluid increases along a streamline while elevation remains constant, what happens to its static pressure?
