Heat and Thermodynamics Facts with Pictures

Q: It is the way heat is transferred from one area to another when there is a “bulk movement of matter”.It is the transfer of heat by motion.

A: Convection. It is the movement of huge amounts of material, taking the heat from one area and placing it in another.

Q: The transfer of heat by means of electromagnetic waves(light), which require no physical medium for the transfer. (e.g. , water or air)

A: Radiation. is the energy carried by electromagnetic waves (light). Those waves could be radio waves, infrared, visible light, UV, or Gamma rays.

Q: It is a situation where the heat source and heat sink are connected by matter. It happens when the source and the sink are connected.

A: Conduction. It is the transfer of heat by successive molecular collisions.

Q: What is process of making heat by rubbing things together?

A: Friction. It is the force that resists relative motion between two bodies in contact.

Q: What do you call a device that measures temperature?

A: Thermometers are devices that measures temperature. There are thermometers to measure your body temperature, the temperature in your oven, and even the temperature of liquid oxygen.

Q: What is the tendency of matter to change in volume,size or length in response the change of temperature through heat transfer?

A: Thermal Expansion, the general increase in the volume of the material as its temperature is increased.

Q: What do you call the opposite of expansion which shrinks the object when heat is removed?

A: The opposite of expansion is contraction. If things expand with the addition of heat, it makes contract or shrinks when heat is removed.

Q: It’s a state of matter that has a small group of atoms with nearly all of the kinetic energy taken out of the system. What is it and who created it?

A: Its Bose-Einstein Condensate , is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero. Invented by Satyendra Nath Bose and Albert Einstein....
