Vedclass · Answer

(B) physical process involves a change in the state of matter without changing the chemical composition of the substance. In $II$ (Ice $\rightarrow$ Water) and $III$ (Water $\rightarrow$ Steam),only the physical state changes,so these are physical processes.$A$ chemical process involves the formation of new substances with different chemical properties. In $I$ (a neutralization reaction) and $IV$ (hydrolysis of starch into glucose),the chemical composition changes,so these are chemical processes.Therefore,the physical processes are $II$ and $III$,and the chemical processes are $I$ and $IV$.

Column $X$	Column $Y$
$(1)$ Starch	$(P)$ Found in animal skeletal tissues
$(2)$ Glycogen	$(Q)$ Stored food form in plants
$(3)$ Chitin	$(R)$ Provides strength in sclerenchyma
$(4)$ Lignin	$(S)$ Stored food form in animals

Identify the physical and chemical processes from the following:
$I - Ba(OH)_2 + H_2SO_4 \rightarrow BaSO_4 + 2H_2O$
$II -$ Ice $\rightarrow$ Water
$III -$ Water $\rightarrow$ Steam
$IV -$ Starch $\rightarrow$ Glucose
Which of these represent physical processes and chemical processes respectively?
