1 Kg of water approximately equals 1 L. What's the volume of a quarter Kg of water?

Q.
1 Kg of water approximately equals 1 L.
Weight of a water-filled cubical container having base area 2500 sq. cm is 25 Kg. Find the level of water inside the container.

Q. 1 Kg of water approximately equals 1 L.
The inside length of a cubical container is 50 cm and weighs 500 g. What would be the total weight of the container if water is filled up to the brim?

Q. What is the relative density of a block of mass 15 kg whose volume is equal to the volume of 6 kg water at $4^{\circ }C$?

Q. The density of water at $4^{o}C$ is $1.0\times {10}^{3}kg{m}^{-3}$. the volume occupied by one molecule of water is approximately:

Q. The air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when $1m^3$ of water cools by $1^{\circ }C$ will raise the temperature of a much larger volume of air by $1^{\circ }C$. Find this volume of air. The specific heat of air is approximately $1kJ/k{g}^{\circ }C$. Take the density of air to be $1.3kg/m^3$.
