Fresh tomato is a better source of vitamin C than canned tomatoes. Why?
Text Solution
Verified by Experts
In case of canned tomatoes, ascorbic acid (vitamin C) gets oxidised by aerial oxygen to dehydroascorbic acid for which amount of vitamin C is reduced. But for fresh tomatoes, there is no reduction of amount of vitamin C. That is why fresh tomatoes are better source of vitamine C than cannot tomatoes

Let us consider 1 mol of gas. If It Is an ideal gas then (Poverset-V)/(RT) = 1 where , overset-V = molar volume of a gas For a non-ideal gas this quotient may not be equal to 1. It can also be less than or greater than 1. Therefore, the above quotient is defined as compressibility factor Z. Z = (Poverset-V)/(RT) = (Molar volume of real gas)/ (Molar volume of ideal gas) The compressibility factor of real gases can be written as Z = (Poverset-V)/(RT)=1+B/overset-V+C/overset-(v^2)+D/overset-(v^3)......(Viral equation) Where B,C,D are called virial coefficients and are dependent on the nature of the gas and temperature. B=(b-a/(RT)) .At Boyle’s temperature,second virial coefficient becomes zero. when Zgt1 repulsive forces are dominant and when Zlt1 the forces of attraction are dominant. Which of the following statements is correct ?
Can we ever attain any temperature lower than the absolute zero temperature .Why?
