Question

Calculate the product of boiling point of water and melting point of water in Celsius scale.
A. ${0^ \circ }C$
B. ${273^ \circ }C$
C. ${100^ \circ }C$
D. ${373^ \circ }C$

Answer 1

Hint:Water is a transparent, tasteless, odorless, inorganic compound. The molecular formula of water is ${H_2}O$. Two hydrogen atoms covalently bond to one Oxygen atom to form a water molecule. Water exists in all the three states, solid, liquid and gas. It changes according to the temperature. At boiling point, water changes into water vapour and at melting point ice changes into water. Find the temperatures at when these two phenomena happen and multiply them to get the required answer.
Complete step-by-step solution:We are given to calculate the product of boiling point of water and melting point of water in Celsius scale.
Water is an inorganic compound which is formed by hydrogen and oxygen. Hydrogen and oxygen covalently bond to form water. Hydrogen and Oxygen both are non-metals.
Water is also known as the universal solvent as most numbers of solutes are soluble in water. 70% of earth’s area is composed of water. Distilled water, the water with no added minerals or chemicals, is colorless, odorless and tasteless.
Water changes into ice at freezing point and ice changes into water at melting point. The melting point of water in Celsius scale is ${0^ \circ }C$
Water vapor changes to water at condensation point and water changes into water vapour at the boiling point. The boiling point of water in Celsius scale is ${100^ \circ }C$.
Product of boiling point of water and melting point of water in Celsius scale is ${0^ \circ }C \times {100^ \circ }C = {0^ \circ }C$ (anything multiplied by zero results zero).

Therefore, the correct option is Option A.

Note: The temperature of Freezing point and melting points of water are equal which is ${0^ \circ }C$; the temperature of boiling point and condensation point of water are also equal, which is ${100^ \circ }C$. Temperature can also be mentioned in Fahrenheit or Kelvin scale other than Celsius scale. Do not confuse between melting point and boiling point as one involves ice and other involves water vapour.
