HELP!!! GCSE Chemistry Controlled Assessment

I have just started doing my chemistry controlled assessment. I am on the part in which i have to evaluate my data with secondary data however I cannot because I cannot find any secondary data. If anyone else can provide me links to my topic of my controlled assessment of secondary data, I will thank you so much.

The topic of my chemistry controlled assessment is “how much energy is transferred as heat when acids react with alkalis.”

The factor I decided to choose is concentration. Please help me with my chemistry controlled assessment.

The reaction between acids reacting with alkalis is called neutralisation.

Here are a few key terms you might want to research/read on,
1) heat capacity

2) specific heat capacity

Hint: the solution making up the acids and alkalis are water.

3) Maybe a bit fancier term at GCSE, but; enthalpy of neutralisation

Thank you so much! That helped me a lot. Also, just wondering, do you know what to write for physics controlled assessment for background information?

My topic is about how factors that can affect the output voltage of a potential divider circuit?

Hah, well that seems to me like an interesting project. Thing is, do you have an idea on what are the possible factors though? I am a chemist by trade, though I am OK with electrochemistry, i am a bit rusty with a potential divider circuit.
