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. Temperature is measured with a thermometer


Mass is a measure of the amount of matter in an object. ... Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity.


Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.


Analytical, and the related verb analyze can both be traced back to the Greek verb, analyein — "to break up, to loosen." If you are analytical, you are good at taking a problem or task and breaking it down into smaller elements in order to solve the problem or complete the task


Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. ... When electrical charges are not moving, electricity is called static electricity.


Dimensional analysis is the use of a set of units to establish the form of an equation, or more often, to check that the answer to a calculation is physically sensible. ... This would be read as "the dimensions of density are the dimension M divided by the dimension L cubed


Flow Flowing fluids are characterized by a quantity called the flow rate, which is defined as the volume of fluid flowing through an area each second. In a pipe or other enclosed region, the flow rate can be expressed in terms of the fluid speed and the cross-sectional area of the pipe.
