Does frozen water have kinetic energy? As water freezes, it does so because after thermal energy leaves the particles (freezing is exothermic), the average translational+rotational kinetic energy decreases, but the total average kinetic energy does not… and the temperature does not change either. What happens to the average kinetic energy of the water molecules in […]
How are S waves and P waves similar?
How are S waves and P waves similar? How are S waves and P waves similar? They shake the ground. They travel through liquids. They arrive at the same time. Which phrase describes a feature of an earthquake epicenter? region directly above the focus. Which phrase describes a lava plateau? Which phrase describes a lava […]
Why the image is blurry after increasing magnification?
Why the image is blurry after increasing magnification? The light intensity decreases as magnification increases. There is a fixed amount of light per area, and when you increase the magnification of an area, you look at a smaller area. So you see less light, and the image appears dimmer. How can you increase the resolution […]
What body parts do frogs use for protection?
What body parts do frogs use for protection? Different species of frogs have different kinds of protection. Some have poison glands in their skin, like a chemical warfare tactic !. The skin will secret and cover the body with the poison and this will deter the enemy from eating them. Some use colors to protect […]
What is the major function of muscles?
What is the major function of muscles? The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. What are four disorders of the […]
What are the 5 factors that affect reaction rate?
What are the 5 factors that affect reaction rate? Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, […]
What types of evidence can be used to support a claim?
What types of evidence can be used to support a claim? These categories are Fact, Judgment, and Testimony. This page explores the types of evidence used in argumentation. See also the page on logic and argumentation. What to do when you are wrongly accused? Steps to Take If You Are Falsely Accused of a Crime […]
Why do resistors decrease resistance in parallel?
Why do resistors decrease resistance in parallel? Resistors in parallel In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference across them. The current through them will be different if they have different […]
What is the pineal gland responsible for?
What is the pineal gland responsible for? The main function of the pineal gland is to receive information about the state of the light-dark cycle from the environment and convey this information to produce and secrete the hormone melatonin. What happens if the pineal gland is damaged? If the pineal gland is impaired, it can […]
