Answer:
The mass of water 
= 39.18 gm
Explanation:
Mass of iron 
= 32.5 gm
Initial temperature of iron 
= 22.4°c = 295.4 K
Specific heat of iron 
= 0.448 
Mass of water =
Specific heat of water 
Initial temperature of water 
= 336 K
Final temperature after equilibrium 
= 59.7°c = 332.7 K
When iron rod is submerged into water then
Heat lost by water = Heat gain by iron rod
( - ) = ( - )
Put all the values in above formula we get
× 4.2 × ( 336 - 332.7 ) = 32.5 × 0.448 × ( 332.7 - 295.4 )
= 39.18 gm
Therefore the mass of water = 39.18 gm
Unlike solid matter, where particles are tightly packed and slightly vibrating, or gas, where particles go around everywhere and are extremely loose, a liquid has particles that are loosely packed but are still in slight contact with each other. Hope that's good enough
