- proteins
- molecules required for the survival, growth, and repair of cells
- specific heat
- when the temperature of 1 gram of a material changes 1 degree Celcius
- less developed
- countries that are economically and technologically poor
- proteins
- molecules required for the survival, growth, and repair of all cells
- nuclear energy
- energy that is created from the nucleus of an atom
- calorimeter
- a device oftem used when measuring specific heat, is designed to prevent the transfer of energy between a physical system and the enviornment
- metabolism
- rate of energy use
- qualitative data
- a non numerical manner of reporting and collecting data; "the words to explain and analyze the facts."
- fossil fuels
- coal, natural gas, and patroleum, burning them produces not only heat and light, but also considerable amounts of Carbon Dioxide
- fermentation
- the way yeast cells obtain energy to live and reproduce by digesting sugar through this process
- Law of Conservation of Energy
- energy cannot be created or destroyed
- joule
- commonly used unit of energy; one calorie is 4.2 of them
- energy flow diagram
- illustrates the pathways energy takes during any transfer or series of transfers
- equilibrium
- natural balance
- optimum
- where an organism thrives the most
- mechanical energy
- energy of motion commonly associated with moving machines and devices
- thermal energy
- energy of heat
- yeast
- single-celled fungi
- Kinetic Theory
- States that the atoms and molecules of all substances are in motion and that at higher temperatures there is faster movement. It was proposed by Gustave Hirn.
- First Law of Thermodynamics
- states that all heat entering a system adds that amount of energy to the system
- atoms
- all materials are made up of these tiny "building blocks"
- homeostasis
- the maintenance of stability in an organisms internal enviornment regardless of external changes
- calorie
- a commonly used unit used to measure energy; the amount of energy required to raise the temperature of water 1 degree Celcius
- per capita
- values that indicate the average amount of an item or resource available to each person living in a given country
- molecules
- atoms bond together to form these bigger structures
- poikiliotherms
- changable body heat or temperature
- more developed
- countries that are economically and technologically rich
- kinetic energy
- energy of motion
- homeotherms
- cannot change body heat
- quantitative data
- a numerical manner of reporting and collecting data; "the facts and data to prove the words"
- thermal conduction
- movement of thermal energy through a material
- potential energy
- stored energy of position
- hidden costs
- effects of a process or action that do not involve obvious costs in the short term but that do have less apparent negative consequences such as enviornmental damage and/or resource depletion, in both the short and long term.
- Cellular Respiration
- a chemical process that takes place within the cells of all organisms
- Second Law of Thermodynamics
- heat will always flow from areas of higher temperature to areas of lower temperature
- Carbon Dioxide
- a colorless odorless gas; it is a natural part of Earth's atmosphere and is important to all life on our planet.
- physical system
- any set of matter within a defined area
- Caloric Theory
- The theory by Joseph Black, an object heats up when caloric from another object flows into it; an object cools down when caloric flows from it to another object
