Thermodynamics Basics
This term describes the study of the effects of work, heat flow, and energy on a system.
What is thermodynamics?
This type of heat transfer occurs through direct contact from molecule to molecule.
What is conduction?
This is defined as force applied over a distance and is measured in joules.
What is work?
This is the movement of electrons through a conductor.
What is electricity?
This term refers to the ratio comparing effort force to resistance force.
What is mechanical advantage?
This is the average kinetic energy of particles in an object and is measured in degrees.
What is temperature?
This type of heat transfer involves the movement of fluids like liquids or gases.
What is convection?
This form of energy is stored energy due to position or configuration.
What is potential energy?
This quantity represents the flow of electric charge and is measured in amperes.
What is current?
This type of mechanical advantage is theoretical and ignores friction.
What is Ideal Mechanical Advantage (IMA)?
This occurs when all kinetic energy is removed from an object and equals 0 K.
What is absolute zero?
All objects gain and lose thermal energy through this process, even in empty space.
What is radiation?
This is the energy of motion, from moving atoms to moving objects.
What is kinetic energy?
This is the force or “pressure” that causes current to flow in a circuit.
What is voltage?
This type of mechanical advantage accounts for frictional losses.
What is Actual Mechanical Advantage (AMA)?
This law states that if two systems are in thermal equilibrium with a third, they are in equilibrium with each other.
What is the Zeroth Law of Thermodynamics?
This law states that thermal energy naturally flows from hot objects to cold objects.
What is the Second Law of Thermodynamics?
This describes the rate at which work is done or energy is transferred.
What is power?
This property opposes the flow of current and is measured in ohms.
What is resistance?
This simple machine has a fulcrum located between the effort and resistance forces.
What is a first-class lever?
This term refers to the total kinetic energy of particles transferred due to a temperature difference.
What is thermal energy (heat)?
This concept measures how evenly thermal energy is distributed within a system and always tends to increase.
What is entropy?
This principle states that energy cannot be created or destroyed, only transformed.
What is the Law of Conservation of Energy?
This law mathematically relates voltage, current, and resistance.
What is Ohm’s Law?
This occurs when multiple simple machines are used together so their advantages multiply.
What is a compound machine?
