Question

Which of the following statements are true? Check all that apply

A. Liquid water expands with increasing temperature above 4°C
B. Solid ice is less dense than liquid water
C. Water contracts as it freezes at 0°C
D. Liquid water expands with increasing temperature between 0°C and 4°C.

Answer 1

A. Liquid water expands with increasing temperature above 4°C

B. Solid ice is less dense than liquid water

Step-by-step explanation:

(A) Liquid water expands with increasing temperature above 4°C

This is correct : Above 4°C, increase in the temperature causes the liquid water to expand.

(B) Solid ice is less dense than liquid water

This is correct: frozen water molecules ( solid ice ) take a more defined crystalline structures which is less dense than that of the molecules in liquid form.

(C) Water contracts as it freezes at 0°C

wrong: rather water contracts on heating from 0°C to 4°C

(D) Liquid water expands with increasing temperature between 0°C and 4°C

wrong: rather liquid water expands with increasing temperature above 4°C
