How do you stop evaporation? Cool the water down or limit its exposure to heat by keeping it in the shade, adding ice or cooling with refrigerated pipes. This lowers the kinetic energy available to the water molecules, which slows the evaporation rate. How quickly does boiling water evaporate? If we continue heating, it will […]
What kills bed bugs instantly?
What kills bed bugs instantly? While some bugs will die in the washing machine, it’s the heat of the dryer that will kill more of them. At least 60 minutes on a high-heat setting should do the trick, according to New York State Integrated Pest Management. Immediately dispose of the used plastic bags and put […]
What is systematic error and examples?
What is systematic error and examples? An error is considered systematic if it consistently changes in the same direction. For example, this could happen with blood pressure measurements if, just before the measurements were to be made, something always or often caused the blood pressure to go up. What are examples of systematic errors? For […]
What is the relationship between distance and strength in both electric and magnetic fields?
What is the relationship between distance and strength in both electric and magnetic fields? Magnetic Fields Varying as an Inverse Cube For both monopoles and dipoles, the field strength decreases as the distance from the source increases. , often called the inverse square law. For electric dipoles, the field strength decreases more rapidly with distance; […]
What is the main reservoir of phosphorus on Earth?
What is the main reservoir of phosphorus on Earth? Explanation: The reservoir of phosphorus in ecosystems is rock, where it is bound to oxygen in the form of phosphate. As phosphate-rich rocks are exposed and eroded, rainwater dissolves the phosphate. Dissolved phosphate is abosrbed through the roots of plants. How are humans involved in the […]
What are the three ways to transfer charge?
What are the three ways to transfer charge? Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept […]
Does distance have a direction?
Does distance have a direction? Distance does not include a direction. Measurements that do not include a direction are called scalars. Displacement is the overall change of position of an object. Measurements that include a direction are called vectors. What formula is V u at? v=u+at is the first equation of motion. In this v=u+at […]

What makes the Colour of a solution?
What makes the Colour of a solution? All materials absorb photons of some energy. But only substances that absorb photons of visible light will have colour. A solution that appears blue green absorbs red light; a purple solution absorbs green light (see Box 2). Is vinegar an acid-base indicator? A solution with a pH between […]
What are 4 ways to increase the strength of an electromagnet?
What are 4 ways to increase the strength of an electromagnet? Answer: We can make the electromagnet stronger by increasing the current, the number of turns or by putting in a soft iron core. wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the […]
