Specific Heat
The units of thermal energy
What are Joules?
The ___ increases when the average kinetic energy of the particles in a material increases.
What is temperature?
Thermal energy that flows from a higher to a lower temperature is ____.
What is heat?
We learned in class about this many laws of thermodynamics.
What is two?
In this system, a furnace heats the water that is then pumped to radiators around the building.
What is a radiator system?
This is represented by the letter C and has the units J/(kg*C).
What is specific heat?
This is the sum of the kinetic energy and the potential energy of all of the particles that make up an object.
What is thermal energy?
Thermal energy is transferred through matter by direct contact of particles by _____.
What is conduction?
Thermodynamics is the study of the relationship among thermal energy, heat, and _____.
What is work?
This is a heat engine that burns fuel in internal chambers.
What is an internal combustion engine?
This instrument is used to measure the specific heat of a substance.
What is a calorimeter?
Thermal energy that does not require matter is ____.
What is radiation?
The transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another.
What is convection?
This law of thermodynamics states that heat never flows spontaneously from a lower to a higher temperature.
What is the Second Law of Thermodynamics?
This is a device that transforms thermal energy into mechanical energy.
What is a heat engine?
Water has a specific heat of 4,184 J/(kg*℃). This amount of energy is needed to increase 1 kg of water by 10℃.
What is 41480 J?
In radiation, this type of wave transfers radiant energy.
What are electromagnetic waves?
Heat always flows from the warmer object to the _____ object.
What is cooler?
Besides doing work on the system, this is another way to increase the thermal energy of a system.
What is adding heat to the system?
This device transfers thermal energy from a cooler region to a warmer region.
What is a refrigerator?
A substance with a mass of 5 kg transfers 8,000 Joules of heat to its surroundings when the temperature drops 12℃.This is that substance's specific heat.
What is 133 J/(kg℃)?
In this form of thermal energy transfer, the density of the substances play a key role.
What is convection?
These are used to reduce the transfer of thermal energy from one place to another.
What are insulators?
This machine seemingly defies the second law of thermodynamics.
What is a refrigerator?
This is a heating system that absorbs radiant energy from the Sun.
What is a solar collector?
