Thermal energy from temperature change
In a greenhouse model investigation, a sample of mass \(0.2\,\text{kg}\) has specific heat capacity \(870\,\text{J kg}^{-1}\text{K}^{-1}\) and warms by \(19\,\text{K}\). Calculate the thermal energy transferred. Enter the numerical result and choose the interpretation that matches the physical meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
