Question 1

Density

Answer 1

Substance as its mass per unit volume

Question 2

Density equation

Answer 2

Density(p)(kg/m3) =mass(m)(kg) / volume(v)(m3)
- p=m/v
- m=pv
- v=m/p

Question 3

Solid property

Answer 3

• Cant flow
• Fixed shape
• Fixed volume
• Higher density

Question 4

Liquid property

Answer 4

• Can flow
• Fit container shape
• Fixed volume
• Medium density

Question 5

Gas density

Answer 5

• Can flow
• Fill container
• Can change volume
• Low density

Question 6

Latent heat of fusion (LF)

Answer 6

energy needed to change state of 1kg from solid to liquid at boiling point

Question 7

Latent heat of fusion equation

Answer 7

Latent heat of fusion(LF) = Energy(E)(j) / mass(m)(kg)

Question 8

Latent heat of vaporisation (Lv)

Answer 8

energy needed to change state of 1kg from liquid to vapour at boiling point

Question 9

Latent heat of vaporisation equation

Answer 9

latent heat of vaporisation(Lv) = Energy(E)(j) / mass(m)(kg)
