Exam-style question
Try this first
A 2 kg block of metal is heated, causing its temperature to rise by 15 °C. If the specific heat capacity of the metal is 500 J/kg°C, calculate the thermal energy absorbed by the metal. Scenario focus: use centripetal acceleration in a distinct A-Level Physics context and identify the relevant physical quantity before choosing the answer.
Model answer
What a good answer should say
- The thermal energy absorbed by the metal is 15000 J.
Explanation
Why this works
The correct answer is The thermal energy absorbed by the metal is 15000 J.. This option is correct for Thermal physics because it applies the centripetal acceleration idea in the stem and keeps the relevant quantity, unit, and physical conclusion together.
The alternatives either use a neighbouring formula, omit a required variable, or describe a different physical situation.
