Dear Student,
4- Tea kettle is made up of metal because a metal is a good conductor of heat and hence it is provided with ebonite handle which is insulator in nature so we do not burn our hands.
5- The scientific reason to drink hot tea in china cup is that china cup is a bad conductor of heat so it will protect our hand from heat and will also keep the tea hot as long as it can.
Regards
