Answer 1

$\huge\mathfrak\pink{Answer}$

In summer, the atmospheric temperature is favourable for microbial growth. Foodstuffs like 'dal' which kept open for a long time favours the growth of microbes. The microbes release various gases as byproduct and these gases form foam on the surface of foodstuffs having more water content.
