Calorie = 1,000 calories

Calorie is kilocalorie

Question 12

Joule

Answer 12

Standard unit of energy

Question 13

Law of conservation of energy

Answer 13

The amount of energy is constant and is constantly being converted from one form to another.

Energy is neither created nor destroyed, but only converted to other kinds of energy

Question 14

Internal energy

Answer 14

Sim of all ke and pé of the particles comprising the system

Question 15

Zeroth law of thermodynamics

Answer 15

Temp of A=B
B=C
Therefore A=C and no heat will flow between

Question 16

First law of thermodynamics

Answer 16

A Change in the internal energy of a system is equal to the sum of the heat flow of the system and the work by/on the system

Question 17

Endothermic

Answer 17

Energy flows into the system

Question 18

Exothermic

Answer 18

Energy flows out of system

Question 19

Expansion

Answer 19

Work done by the system

Question 20

Compression

Answer 20

Work done on the system

Question 21

Second law of thermodynamics

Answer 21

Thermal contact heat flows from hot body to cold body

Question 22

Third law of thermodynamics

Answer 22

It is not possible to lower the temp of an object to absolute zero

There is always some energy in object

Question 23

Temperature is

Answer 23

Measurement of the tendency to gain or lose heat

Question 24

Heat is

Answer 24
