Changes in the freezing point and boiling point of a solution depend primarily on the number of solute particles present rather than the kind of particles. Such properties of solutions are called colligative properties (from the Latin colligatus, meaning “bound together” as in a quantity). What...

Synovial mesenchymal stem cells (MSCs) have high freeze–thaw tolerance, whereas human umbilical vein endothelial cells (HUVECs) have low freezing tolerance. The differences in cell type-specific freeze–thaw tolerance and the mechanisms involved are unclear. This study thus aimed to identify the bio...
On the first single fromThe Low End Theory, Q-Tip and Phife Dawg reminisce about kicking rhymes and practicing their stage presence on Linden Boulevard in Jamaica, Queens. The casual, laid-back mood brings out the duo’s chemistry. Both are on point all the time, but Phife stands out wit...
3. Depression of Freezing Point: This property refers to the lowering of the freezing point of a solvent when a solute is added. The presence of solute particles interferes with the ability of the solvent molecules to form a solid structure. 4. Osmotic Pressure: This is the pressure required...
