Energy changes in a system, and the ways energy is stored before and after such changes

Question

A. Energy needed to raise the temperature of one kilogram of a substance by one degree Celsius
B. Energy needed to cool one kilogram of a substance by one degree Celsius
C. Temperature change of a substance
D. Mass of a substance

Answer

Energy needed to raise the temperature of one kilogram of a substance by one degree Celsius

Explanation

The correct option is "Energy needed to raise the temperature of one kilogram of a substance by one degree Celsius". Energy needed to raise the temperature of one kilogram of a substance by one degree Celsius is right because it directly matches Energy changes in systems: Identify change in thermal energy in joules, mass in kilograms, specific heat capacity in joules per kilogram per degree Celsius and temperature change in degrees Celsius.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.

Common mistake

Confusing Units of Measurement

Students often confuse joules with kilograms when identifying thermal energy changes.

Always remember that thermal energy is measured in joules, while mass is measured in kilograms. Keep the units distinct when performing calculations.
