Q1 QUESTION 1 OF 26
Page 1
, Energy can be neither created nor destroyed although it can change form
CORRECT ANSWER
Law of Conservation of Energy
RATIONALE
Energy transformation adheres to the principle that total energy remains constant within an isolated system,
illustrating that while energy may shift between kinetic, potential, or thermal forms, its quantity is preserved. This
fundamental law underpins thermodynamic processes and is for understanding energy interactions in physical
systems.
Q2 QUESTION 2 OF 26
Amount of energy required to raise one gram of water by 1 degree C
CORRECT ANSWER
Calories
RATIONALE
Calories quantify the specific heat capacity of water, representing the energy needed to elevate the temperature of
one gram by one degree Celsius. This measurement is fundamental in thermodynamics, illustrating heat transfer and
energy requirements in biochemical reactions and physiological processes.
Q3 QUESTION 3 OF 26
The quantity of heat (q) that an objects absorbs or releases when it experiences a temperature change of 1
degree C. Dependent on the mass (extensive property)
CORRECT ANSWER
Heat Capacity (C)
RATIONALE
Heat capacity quantifies the amount of heat required to change an object's temperature by one degree Celsius,
directly related to its mass, making it an extensive property. This principle illustrates the relationship between
energy transfer and temperature change in thermodynamic systems.
