The change in volume of a gas with change in temperature is plotted on a graph, as shown in he figure. Calculate the ratio of density at `50 ^(@)C and 100 ^(@)C`

Text Solution

Verified by Experts

Volume at `50^@C=20 cm^3`
Volume at `100^@C=30cm^3`
Density `=("mass")/("volume")`
Ratio of density `=(30)/(20)=3/2=3:2`
