Particle Model Flashcards
Which of the three states of matter can be compressed?
Gas
What is the equation for density?
Density = mass / volume
What is the name for the equipment we use to work out an objects volume?
Displacement can
What is specific heat capacity?
The amount of energy needed to raise 1kg of the substance by 1 degrees Celsius
What is specific latent heat?
The amount of energy needed to change the state of 1kg of the substance
Which is higher, the specific heat capacity or the specific latent heat for substance?
Specific latent heat
Which is higher, the specific latent heat of melting, or the specific latent heat of evaportation?
Specific latent heat of evaporation
When a substance changes state, what happens to its temperature?
It stays the same (until ALL the particles have changes state)
Why does increasing the temperature of a fixed volume of gas increase the pressure?
The particles hit/collide with the sides more often with greater force
How do you convert/calculate temperature in degrees Celsius to degrees Kelvin?
Add 273 to the degrees Celsius
