Collect the melting point of
Ice

Collect the melting point of diethylether

Collect the melting point of methane from a databook

Collect the melting point of Ethyl alcohol

Answer the following The triple-point of water is a standard fixed point in modern thermometry, why? What is wrong in taking the melting point of ice and the boiling point of water as standard point 1 as was originally done in the celsius scale?

Stability of a crystal is reflected in the magnitude of its melting points'. Comment. Collect melting points of solid water.ethyl alcohol, diethyl ether and methane from a data book. What can you say about the intermolecular forces between these molecules?

Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason). Examine the statements carefully and mark the correct answer according to the instruction given below: STATEMENT-1: The melting point of ice decreases with increase of pressure. STATEMENT-2: Ice contracts on melting .
