P1- Moving and Storing heat Flashcards
What is gained when a substance is heated?
Kinetic energy (KE)
what makes the solids and the liquids to boil and how?
the liquid and the gases particles move around faster and the solid vibrates faster
what is energy measured on? and what is the unit?
and absolute scale, joules (J)
What is temperature a measure of?
Hotness
is temperature a measure of an absolute scale?
no
if the greater the distance on temp will the rate of cooling be faster or slower?
faster
what does specific heat capacity (shc) tell me?
how much energy stuff can store
what is the definition of specific heat capacity?
is the amount of energy needed to raise the temp of 1KG of a substance by 1 degree Celsius.
how many joules are needed to warm 1kg of water by 1 degree Celsius?
4200j
how would you work out shc?
Energy= Mass x Specific heat capacity x temperature change
