heat and energy

What is thermodynamics

The study of energy and energy transfer

What is energy

The ability to do work

what is kinetic energy?

energy of motion

what is potential energy?

energy that is stored by and object as a result of its composition or position

what is heat

the energy transferred between two objects as a result of a difference in temperature between them

what is thermal energy

sum of the potential energy of all the particles of an object or substance

what temperature

the measure of the average kinetic energies of all the particles of an object or substance

what is the law of conservation of energy

energy cannot be created or destroyed (it’s only converted into another form)

what is a system

any sample that is under observation

what is a surrounding

everything else other than the system

what is an open system

a system that can exchange both energy and matter with its surroundings

what is a closed system

a system that can exchange energy but not matter with its surroundings

what is an isolated system

a system that cannot exchange energy or matter with its surroundings

what do the terms stand for?

q = heat (J)

m = mass (g)

c = specific heat capacity (J\g*c)

t = change in temperature

= final temp - initial temp
