the ability to do work or produce heat
force acting over a long distance
A flow of energy due to a temperature difference (larger differences in particle kinetic energy results in more _____transferred)
a property that does not depend on the pathway (change in energy)
measure of the average kinetic energy of the particles that make up the sample (higher____means faster moving particles)
energy of motion KE=1/2mv^2
energy of position or composition
high potential energy (potential to release energy as heat)
the focus of observations
energy flows out of a system (PE decreases)
77 degree pool, a campfire
energy flows into a system(PE increases)
entering a hottub, photosynthesis
amount of energy required to raise the temperature of one gram of water by one celsius degree
1000 calories (kilocalorie)
1 food calorie
specific heat capacity
the amount of energy required to change the temperature of one gram of a substance by one celsius degree
First law of thermodynamics
the energy of the universe is constant
energy flow as heat due to a chemical reaction
breaking large pretroleum molecules to obtain a larger quanity of molecules
work can no longer be preformed
societl dependence on fossil fuels is the effect of the ecosystem and climate, natural process that moderates our temperature
recent trend that increasers our temperatures explained by increasing greenhouse gases in the atmosphere
spontaneous radiation of a particle (alpha, beta, or gamma)
result of a large nucleus being split to form two smaller ones
result of small nuclei being smashed together to form a larger one
Band of stability
region of proton to neutron ratio, which accompany stable isotopes
Second law of thermodynamics
The entropy of the universe is always decreasing
