Which one of the following processes will produce hard water ?

In curing cement plasters water is sprinkled from time to time. This helps in :

In an irreversible process taking place at constant $T$ and $P$ and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria:

The internal energy change when a system goes from state $A$ to $B$ is $40 \,k J / mol$. If the system goes from $A$ to $B$ by a reversible path and returns to state $A$ by an irreversible path, what would be the net change in internal energy?

The de-Broglie wavelength of a tennis ball of mass $60\, g$ moving with a velocity of $10 m / s$ is approximately : (Planck's constant, $h=6.63 \times 10^{-34} \,Js$ )

Several blocks of magnesium are fixed to the bottom of a ship to :

When $U^{238}$ nucleus originally at rest, decays by emitting an alpha particle having a speed u, the recoil speed of the residual nucleus is

A circular disc $X$ of radius $R$ is made from an iron pole of thickness $t$, and another disc Y of radius $4R$ is made from an iron plate of thickness $\frac {t}{4}$. then the relation between the moment of inertia $I_X$ and $I_Y$ is

If a body loses half of its velocity on penetrating $3 \,cm$ in a wooden block, then how much will it penetrate more before coming to rest?

An aqueous solution of $1M \,NaCl$ and $1M \,HCl$ is:

When $KMnO_4 $acts as an oxidising agent and ultimately forms $MnO^{2-}_4, MnO_2, Mn_2O_3 \, and \, Mn^{2+}$. Then the number of electrons transferred in each case respectively

If in a circular coil $A$ of radius $R,$ current $i$ is flowing and in another coil $B$ of radius $2 R$ a current $2 i$ is flowing, then the ratio of the magnetic fields, $B_{A}$ and $B_{B}$ produced by them will be :

The inductance between A and D is :
