first and second law of thermodynamics

When applying the first law of thermodynamics to a system, when is heat a positive quantity?

• when the system does work
• when the system has work done on it
• when the system absorbs heat
• when the system loses heat
• when no work is done either on the system or by the system

The First Law of Thermodynamics describes the conservation of energy

• True

• False

In the formula of The First Law of Thermodynamics, the ''Q'' represent:

• Change in internal energy

• Energy transferred as heat

• Work done on or by the system

In the formula of The First Law of Thermodynamics, the ''W'' represent:

• Work done on or by the system

• Change in internal energy

• Energy transferred as heat
