Also called thermal energy (symbolized by q) is the energy transferred as a result of a difference in temperature between the system and the surroundings.
Define work.
The energy transferred when an object is moved by a force.
⌂E=__?
D.
⌂E=q+w
Change in energy is equal to the sum of energy transferred as heat and/or work.
How many Joules are in a calorie?
1cal=4.184J
What is an equation which relates change of enthalpy and heat transferred?
qp=⌂E+P⌂V=⌂H
Heat transferred equals the sum of the change of energy with the PV work done by the system.
These two equal the change of enthalpy.
Define specific heat capacity.
The quantity of heat required to change the temperature of 1 gram of the object by 1K
