Question

Water is such a substance which_________ at 0 degree Celsius up to 4 degree Celsius

a) expands on heating
b) Contracts on heating
c) Contracts on cooling
d) Remains unchanged​

Answer 1

Answer is A

Explanation :

Answer 4 degrees turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion ofwater when you cool it to lower temperatures is unusual, since most liquids contract when they're cooled.Nov 4, 2018

Answer 2

Water is such a substance which a) expands on heating at 0 degree Celsius up to 4 degree Celsius.

Explanation:

When ice is heated to a temperature of 0 to 4 degrees Celsius, it compresses. The water molecules become closer together, and the volume of the water decreases. Water, like most other liquids, expands as it is heated above 4 degrees C.

Expands on heating:

• When matter is heated, the average kinetic energy of the particles increases, and this increase in motion increases the average distance between the atoms.

Contracts on heating:

• As a result, water and silver iodide are two substances that contract when heated. Note: It's important to recall the quality that water has while it's between 0 and 4 degrees Celsius.

Contracts on cooling:

• The molecules in solids slow down when they cool. As a result, the molecules are able to move closer together, causing the solids to compress. When solids are heated, they expand.

Remains unchanged​:

• Something that hasn't altered for a long time is said to be unmodified. Prices have stayed essentially stable for several years.
