What does heating do to a substance |
Increases the energy in the thermal energy store Increases kinetic stores of its particles Sometimes called the internal energy ofa substance |
|
|
When you heat a substance, what do you transfer form the chemical store to the objects thermal store |
Energy |
|
|
What happens to the movement of the particles when you heat a substance |
They vibrate and move more because they have more kinetic energy |
|
|
What do you measure energy in |
J, joules |
|
|
The thermal energy of two objects mixed together is the —— of their delegate thermal energies |
Sum |
|
|
The more —————- / —————— something has, the more energy it has |
Mass/ particles |
|
|
It takes more ———— to increase temperature of some material than others |
Energy |
|
|
Some materials that need aloe of energy to gain lots of energy warm up release ———— of energy when they cool down again |
Loads |
|
|
What is the specific heat capacity |
The Change in energy in the substances thermal store needed to raise the temperature of 1kg of that substance by 1 degrees c |
|
|
What is the measurements of specific heat capacity |
J/ kg*c |
|
|
What is the temperature |
Measure of heat |
|
|
What is 0*c in kelvins |
273 k |
|
|
1k increase = |
1*c |
|
|
0k is the ————— |
Equevelent of -273 meaning that it is the lowest lowest |
|
|
What is the equation for change in thermal energy |
Mass(kg) x specific heat capacity(j/kg*c) x change in temperature(0*c) |
|
|
What is a chemical change |
A change that is harder to reverse because it has made a new substance and the atom joint together in different ways |
|
|
What is a physical change |
When the particles rearrange but don’t bind together so no new substance is created This means that it is easy to reverse |
