Write the letter T or F inside each box after deciding which statement is true or false. Then on the
Dox, write the letter of your choice based on the given instructions.
A if both statements are true
B if the 1st statement is false and the 2nd statement is true
C if the 1st statement is true and the 2nd statement is false
D if both statements are false
Entropy changes cannot be measured with a calorimeter like enthalpy chanrges
If the result upon calculation of entropy changes in the universe is a positive value, te process is
reactant-favored.
If the change in free energy, 4G is negative, the reaction is spontanes in the forward direction
It is more convenient to use change in enthalpy, AH, as a criterion of spontaneity than channe in
entropy, AS.
Work is energy used to cause an object with mass to move.
Heat is energy used to cause the temperature of an object to increase.
Heat flow is a directional quantity. Heat flows from a warmer body to a colder body.
The Sl unit of heat is calorie.
