Sarah has four samples of substance sample a 10 ml of olive oil sample b 10 ml of water sample c 20 ml of water sample d 20ml of milk which of the following samples have the same boiling point ?

Samples b 10 mL water and c 20 mL water have the same boiling point.

Water boils at 100 °C no matter how much you have.

The boiling point of a substance is an intensive property — it doesn’t change with the amount of substance.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

consider the reaction below.
