What happens when a solid is dissolved in a liquid? In the simplest case it involves mixing two materials together. The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. Why […]

How do you interpret mean median and mode in research?
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
What are two examples of colloids?
What are two examples of colloids? Examples of colloid are mayonnaise, milk, butter, gelatin, jelly, muddy water. What are the 4 types of colloids? The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many […]
What 3 types of EM waves are dangerous to humans?
What 3 types of EM waves are dangerous to humans? The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them. How long does it take for gamma rays to kill you? Most deaths occur within […]
What are the possible values of n and ML for an electron in a 4 d orbital?
What is the difference between control variable and independent variable?
What is the difference between control variable and independent variable? Independent variable – the variable that is altered during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results. What is the different types of variables? Parts of […]
What phase are cells in when they are not dividing?
What are the 3 field forces?
What are the 3 field forces? Field forces are also called noncontact forces or at-a-distance forces. There are four types of field forces: gravity, electromagnetic forces, and the strong force and the weak force found in atoms. What are two field forces examples? Examples of force fields include magnetic fields, gravitational fields, and electrical fields. […]
