The SI unit of volume is the cubic metre $\left({\mathrm{m}}^3\right)$. The common unit of measuring volume in litre $\left(\mathrm{L}\right)$. Then, $1\mathrm{L}=\_\_\_\_{\mathrm{dm}}^3,1\mathrm{L}=\_\_\_\_\mathrm{mL} \mathrm{and} 1\mathrm{mL}=\_\_\_\_{\mathrm{cm}}^3.$

Find out the incorrect increasing/decreasing order in the following

The kinetic energy of particles of water in three vessels $\mathrm{X},\mathrm{Y}$ and $\mathrm{Z}$ are ${\mathrm{E}}_{\mathrm{X}},{\mathrm{E}}_{\mathrm{Y}}$ and ${\mathrm{E}}_{\mathrm{Z}}$ respectively and ${\mathrm{E}}_{\mathrm{x}}>{\mathrm{E}}_{\mathrm{Y}}>{\mathrm{E}}_{\mathrm{z}}$. Then the temperature of water in the three vessels are
