What is meant by change of state of matter? A change of state is a physical change in a matter. They are reversible changes and do not involve any changes in the chemical makeup of the matter. Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization. Can Matter change its state […]

What happens when a monochromatic beam of light falls on a glass prism? When monochromatic light passes through a glass prism, the light suffers double refraction, one at refracting surface at which it is incident at and the second at the opposite the refracting surface through which it emerges out in the air. What happens […]

What is the external net force? Net external force is the sum of all of the forcing acting on an object. Friction is the force between an object in motion and the surface on which it moves. Friction is the external force that acts on objects and causes them to slow down when no other […]

What kind of graph is best for showing change over time in a set of data? Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time. What is histogram and bar graph? The […]

How do you know if your pipes burst? No Water Coming out of the Pipes/Low Water Pressure If water is gushing out somewhere else, then you won’t have strong pressure or any water coming out of the faucet. If you are currently in the shower and notice a sudden and drastic drop in the water […]

What happens when a wave runs into a barrier? Reflection involves a change in direction of waves when they bounce off a barrier; refraction of waves involves a change in the direction of waves as they pass from one medium to another; and diffraction involves a change in direction of waves as they pass through […]

What type of intermolecular forces does acetone have? Answer and Explanation: 1) Acetone is a dipolar molecule. Therefore, the dominant intermolecular forces between the acetone molecules are dipole-dipole interactions. What kind of intermolecular forces act between two methanol? Methanol is polar, and will exhibit dipole interactions. It also contains the -OH alcohol group which will […]

What are the 4 types of cell signaling? There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine signaling, endocrine signaling, and signaling by direct contact. What type of signaling is epinephrine? When epinephrine binds to its receptor on a muscle cell (a type of G protein-coupled receptor), it triggers […]
