A person living in Shimla observed that cooking food without using pressure cooker takes more time. The reason for this observation is that at high altitude:

(i) Pressure increases

(ii) Temperature decreases

(iii) Pressure decreases

(iv) Temperature increases

<p><span data-teams="true">This is a multiple choice answer as classified in NCERT Exemplar</span></p><p>Option<strong> </strong> (iii) pressure decreases&nbsp;</p><p>At high altitude the pressure is low and therefore, water boils at lower temperature because the vapour pressure becomes equal to atmospheric temperature at low temperature due to which the food takes more time to be cooked without using a pressure cooker.</p>
