How do you calculate accuracy? Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it. What precautions must you take when directly measuring the length of an object? […]

What state has the most kinetic energy?
What state has the most kinetic energy? Energy and State of Matter A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related […]
What is the most important cholesterol number?
What is the most important cholesterol number? When we measure cholesterol and blood fats, we’re really talking about three different numbers: HDL, LDL, and triglycerides. They combine to give you a “lipid profile” score, but the three individual scores are most important. Here are the numbers to strive for: Total cholesterol of 200 mg/dL or […]
What 3 molecules Cannot easily pass through the membrane?
What 3 molecules Cannot easily pass through the membrane? Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by […]

What temperature will solid melt?
What temperature will solid melt? The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid. At that temperature, the solid and liquid states of the substance are in equilibrium. For water, this equilibrium occurs at 0°C. Are temperature and kinetic energy the […]
What sounds have very high amplitude?
What sounds have very high amplitude? The blast of a launching rocket is loud enough to damage people’s hearing permanently. Sound waves created by the rocket will have a very high amplitude. What does it mean when a wave’s amplitude increases? The sound is perceived as louder if the amplitude increases, and softer if the […]
Does water absorb noise?
Does water absorb noise? The same thing happens to sound. As sound travels through a medium such as water, it gets absorbed – caught by the molecules within the medium. They do this by stealing some of the energy from the sound wave. The absorption in sea water is much greater than would be expected […]
In which medium will sound travel the slowest?
In which medium will sound travel the slowest? Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Let’s find out why. Sound moves slowest through a gas. That’s because the molecules in a gas are spaced very far apart. Which […]
