Answer:
0.33 ml
Explanation:
Formula for density: p = m/V (where p is <em>density</em>, m is <em>mass</em> and V is <em>volume</em>)
So, by applying the above formula:
Answer:
In case of plants surface tension help to support the transpiration pull.
Explanation:
Surface tension is a force that hold the molecules in the surface to minimize the surface area.
During evaporation of excess amount of water from the stomata of leaves of plants by transpiration a surface tension is generated.
The generated surface tension helps to maintain the water column within the xylem tissue by the absorption of water from the soil by the roots.

Answer : Option 3) Electrolysis.
Explanation : In the process of electrolysis, decomposition of the chemical is done by passing the electric current from the liquid or the solution containing ions in it. This is the process where compound is broken into ions namely, cations and anions.
Rest all options does not involves chemical decomposition of the compound.
Chromatography is a technique where rates of solute and solvent are compared in a medium where the solute components move at different rates and the separation is obtained.
Distillation simply purifies the liquid or solution by heating or cooling process.
Filtration just involves removal of impurities by using a more porous material device to get purified compound.
Answer: Temperature
Explanation: Temperature is a measure of average kinetic energy of particles in an object. The hotter the substance, higher is the average kinetic energy of its constituent particles. When we heat a substance, the particles that constitute the substance gain some energy and begin to move faster.
