Particle model

Which of the three states of matter can be compressed?

• Liquid

• Gas

• Solid

What is the equation for density?

• Density = mass / volume

  r = m / v

• Density = mass x volume

  r = m x v

• Density = mass + volume

  r = m + v

What is the name for the equipment we use to work out an objects volume?

• Displacement box

• Displacement can

• Displacement cannister

What is specific heat capacity?

• The amount of energy needed to raise 1kg of the substance by 1 0^C

• The amount of water needed to raise kg of the substance by 1 0^C

What is specific latent heat?

• The amount of energy needed to change the state of 10g of the substance.

• 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 a substance?

• The amount of energy needed to raise 1kg of the substance by 1 0^C

• The amount of energy needed to change the state of 1kg of the substance.

• Specific latent heat.

Which is higher, the specific latent heat of melting or the specific latent heat of evaporation?

• Specific latent heat of condensation

• Specific latent heat of evaporation

• Specific latent heat of melting

When a substance changes state, what happens to its temperature?

• It gets higher until ALL the particles have changed state)

• It stays the same (until ALL the particles have changed state)

• It gets lower until ALL the particles have changed state)

Why does increasing the temperature of a fixed volume of gas increase the pressure?

• The particles hit/collide with the sides less often with less force

• 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 10 to the degrees Celsius.

• Add 273 to the degrees Celsius.

• Add 27300 to the degrees Celsius.
