Which of the following statements does not describe the alkali metals? a. most are shiny gray solids that are very soft. b. they easily gain an electron to form ions with a charge of –1. c. they are not found uncombined in nature. d. they react with water to form alkaline solutions.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
