Do I have to memorize kinematic equations for MCAT? Kinematic equations are the foundation to mastering MCAT physics. Yes you have to ‘memorize’ and know the standard formulas, but it goes deeper than that. You have to understand the units, when to use which equation, and be VERY comfortable applying these concepts to the more […]

Which shows the formula for converting from kelvins to degrees Celsius? C = K – 273.15. This formula to convert the temperature in Kelvin to degree Celsius is used for changing the given temperature from Kelvin to degree Celsius. What causes liquid in thermometer to drop? When heated, the molecules of the liquid in the […]

How is temperature determined? Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Does reheating meat kill bacteria? Proper […]

Which is the thinnest layer of the earth? Inner core Which is the thinnest layer of atmosphere? Troposphere What are the 4 atmospheres? The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the […]

How do you do IV push medications? Scrub the end cap on your IV line for 15 seconds with a fresh alcohol pad and let it air dry. Twist the syringe of heparin or citrate into the end of your IV line. “Pulse flush” your IV line with the syringe of heparin or citrate. Before […]

Is iron rusting in the presence of moist air a physical change? Rust is a reddish-brown substance formed on iron when it has been exposed to fresh air and moisture for a long time. This process is a chemical change called rusting. What is the chemical reaction of rusting? Rusting is an oxidation reaction. The […]

What will be the pulse rate during heart attack? A very high or very low heart rate may reveal your risk for heart attack. For most people, a heart rate that’s consistently above 100 beats per minute or below 60 beats per minute for nonathletes should prompt a visit to a doctor for a heart […]

Did Einstein say we Cannot solve our problems with the same thinking we used to create them? The supposed Einstein quote from Skeptic reads “the world we have made as a result of the level of thinking we have done thus far creates problems that we cannot solve at the level of thinking at which […]

How can we make this object move? Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity). Friction is the force between two objects in contact with each […]
