Answer 2

The correct answers to the given questions are:-

(a) The physical state of the point a is solid, b is liquid, c is gas, and d is steam.

(b) The melting point of the substance is 15° C.

(c) The boiling point of the substance is 110° C.

(d) The temperature of the substances while their state changes remain constant.

(e) The melting point of water is 0° C and the boiling point is 100° C, but in this case, it is 15° C, and 110° C. Hence, it is not water.
