The protein molecules in milk (mainly casein) have a negative charge and they naturally repel each other. This stops milk from clumping together and curdling when it’s kept in your fridge. However, if your milk becomes more acidic this changes the proteins so that they start to attract each...

Why can gases and liquids both transmit heat by convection? Why do liquids flow and solids do not? Why do gas molecules enter liquids? Do they enter solids? Why do liquids take the shape of their container? Why do gases condense when they are cooled?
contributing to the fresh, vegetal smell of petrichor.The formation of ozone in the atmospherecan also be a factor if there is a thunderstorm. Lightning is so powerful that it can split molecules of oxygen and nitrogen to form nitric oxide and ozone, which has ...
molecules are in the cell, the new gene is inserted into the chromosome randomly. (The transformed cell is grown in a tissue culture to become a plantlet and eventually a plant.) It’s impossible to control just where the gene gets added; sometimes it ends up in a spot where it can ...
If Phobos and Deimos are examples of D-type asteroids that swung close to Mars and were pulled into orbit, then a sample from Phobos could tell us about the formation and transportation of the first organic molecules to form in the Solar System. But not everyone believes this formation scenar...
Why does temperature difference increase the rate of heat transfer? Why can't polar molecules cross by simple diffusion? Why does diffusion occur in marine organisms? How does heat affect the movement of molecules? Why do gases diffuse?
How do fabrics dry? Liquid water consists of numerous water molecules attracted to one another by cohesive forces. These molecules are in constant motion. The average rate of motion reflects the water temperature. The rate of motion for individual molecules in water will range from high to low....
Why are water molecules partially charged? How does freezing and evaporation affect salinity? How did Antarctica freeze? Why does water heat up and cool down slowly? How does evaporation make water denser? Why are some substances not able to dissolve in water? Why does the density of ocean wa...
