3] solid + Gas
4] solid + Gas, liquid, Gas ​

Answer 1

Answer:

2) solid+ liquid, liquid,gas

Answer 2

Solid + liquid, liquid, gas are the conditions are observed when ‘heat’ is supplied to the substance.

Explanation:

• When a substance is supplied with heat it slowly changes from its solid state to its ‘liquid state’ by melting.  

• This is attained at the ‘melting point’ of the substance. If the heat is increased the liquid absorbs the heat and starts to boil.  

• Once it reaches its boiling point it ‘starts changing’ into its gaseous or vapour state.  

• So the conditions observed when ‘heat’ is supplied to the ‘substance’ are ‘solid + liquid, liquid, gas’.
