Elements in the Periodic Table Non-Metals Very Reactive Metals Not So Reactive Metals

Melting and Boiling Points

Melting and Boiling Points The melting point is the temperature at which a substance changes from a ............ to a .............. solid liquid The boiling point is the temperature at which a substance changes from a ............ to a .............. liquid gas Water melts at .....°C and boils at ........ °C. 100

Material Melting Point (oC) Aluminium 660 Helium -270 Bromine -7 Iron 1537 Water Ethanol -117 Oxygen -218 Nitrogen -210 Material Boiling Point (oC) Aluminium 2467 Helium -269 Bromine 59 Iron 2927 Water 100 Ethanol 79 Oxygen -183 Nitrogen -196

Separation Techniques A Mixture is formed from different substances that are not chemically joined together. Some mixtures are insoluble eg Sand and Water Some mixtures are soluble eg Salt and Water

Fill in the vowels (a,e,i,o,u) to form the name of a method to separate mixtures F_ltr_t_ _n _v_p_r_t_ _ n D_st_ll_t_ _n Chr_m_t_gr_phy M_gn_t_sm Filtration Evaporation Distillation Chromatography Magnetism 2 mins

Separation Techniques 4 mins Separation Techniques Separates magnetic material from non-magnetic materials Filtration Separates a soluble solid by boiling off the liquid Distillation Separates an insoluble solid from a liquid Magnetism Separates liquids with different boiling points Chromatography Separates liquids of different colours Evaporation
