Properties Of Matter Flashcards
What is Specfic Heat Capicity?
The energy required to raise the temperature of 1 kg of a material by 1 degree celsius.
What is the unit for specific heat capacity?
Joules per Kilogram Per Degree celsius (Jkg-1C-1)
To increase different materials tempature, what factors affect a material?
Mass, the tempature change involved, type of material
How do you reduce heat loss in an experiment?
Wrap the experiment in some type of insulating material.
What is specific latent heat of fusion?
The energy required to change the starte of 1 kg of a material from solid to liquid.
What is specific latent heat of vaporisation?
The energy required to change the state of 1 kg of a material from liquid to gas.
What is the unit for Specific Latent Heat Of Fusion/Vaporisation?
Joules per kilogram (J Kg-1)
When do you use the Specific Heat capacity Equation?
When a substance is changing temperature.
When do you use the specific latent heat of fusion/vaporisiation equation?
When a substance is changing state.
Does the temperature of a substance change when it changes state?
NO
What is the definition for pressure?
Pressure is the force acting per metres squared of a surface.
What is the unit for pressure?
Pascals (Pa)
What area of something gives the GREATEST pressure?
The SMALLEST surface area touching the ground/floor
What is the definition of a temperature of a substance?
The measure of the mean kinetic energy of it’s particles.
What is absolute zero?
0 Kelvin (K)
