Heat & Electricity Flashcards
What is Temperature?
The measurement of how hot or cold an object is.
How is temperature determined?
By the average kinetic energy of the particles in the object.
What is temperature recorded by?
*C
What is water’s freezing point?
0*C
What is water’s boiling point?
100*C
What is heat?
Heat is the transfer of energy that takes place between objects of different temperatures.
What happens to a hot cup of coffee?
The coffee will cool down because it loses its heat to the surroundings.
What happens to cold soda?
The drink will warm up because it is taking in heat from the surroundings.
How much heat energy an object has depends on its temperature AND how much of it there is. True/False?
True.
What would heat faster, a 100cm3 beaker of water, or a 200cm3 beaker of water?
100cm3 beaker of water.
If 50J of energy was added to a beaker and there was 10 particles, how many joules of energy would each particle have?
5J
