What volume of alcohol will have same mass as 4.2m-3 of petrol?
Density of alcohol = 8.4 x 10^2 kgm-3, density of petrol =7.2x10^2 kgm-3
Two liquids X and Y having the same mass are supplied with the same quantity of heat. If the temperature rise in X is twice that of Y, the ratio of specific heat capacity of X to that of Y is
