A warmer to a colder body 1 of 10 What is heat a measurement of? Internal energy 2 of 10 What is specific heat capacity? Energy needed to raise the temperature of 1kg by 1 degrees 3 of 10 What is specific heat capacity measured in? Joules per kilogram degree celsius 4 of 10 Equation for energy transfer by specific heat capacity? Energy transferred = mass x specific heat capacity x temperature change 5 of 10 What is specific latent heat? The energy needed to melt/boil 1kg of the material 6 of 10 What is specific latent heat measured in? Joules per kg 7 of 10 How do double glazing windows reduce energy loss? Conduction, the space between is filled with gas or contains a vacuum. The particles are very far apart so it is difficult to transfer energy 8 of 10 Equation for density Mass/Volume 9 of 10 Equation for efficiency Useful energy output (x100%) / Total energy input 10 of 10
