Specific Heat Capacity Flashcards
Materials which gain lots of energy to warm up also release loads of energy to cool down again these materials can store…
A lot of heat
What is the measure of how much energy a substance can store called?
It’s specific heat capacity
What is specific heat capacity?
The amount of energy needed to raise 1kg of substance by 1 degree
What is the formula for specific heat capacity?
E=m(times)c(times)ø
Energy= mass (times) specific heat capacity (times) temp change
What is energies units?
J/KJ
Joules/kilojoules
What is mass units?
KG
What is specific heat capacities units?
J/kg•C
What is temperature changes units
•C
What do materials in heaters usually have?
High specific heat capacitys
Why is water ideal for a central heating system?
Because it has a really high SHC and is a liquid so can flow through pipes
Do concrete and bricks have HSHC?
Yes
Does oil have a higher SHC than water?
No it has a higher boiling point
What does specific heat capacity tell you?
How much energy stuff can store
