What happens to kinetic energy when temperature decreases? When we decrease the temperature, less heat energy is supplied to the atoms, and so their average kinetic energy decreases. When they enter a phase transition, such as freezing from a liquid to a solid, the temperature is not decreasing or increasing, and stays constant. What determines […]
Why the direction of dipole is from negative to positive?
Why the direction of dipole is from negative to positive? showing that the dipole moment vector is directed from the negative charge to the positive charge because the position vector of a point is directed outward from the origin to that point. (Because of overall charge neutrality, the dipole moment is independent of the observer’s […]
What affects the strength of a magnetic field?
What affects the strength of a magnetic field? Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size […]
Why is too much carbon dioxide in the atmosphere a problem?
Why is too much carbon dioxide in the atmosphere a problem? Climate change is primarily a problem of too much carbon dioxide (CO2) in the atmosphere. This carbon overload is caused mainly when we burn fossil fuels like coal, oil and gas or cut down and burn forests. Can carbon dioxide be removed from the […]
Which country has no ocean?

Europe and Africa have 16 landlocked countries each, Asia has 15 states without coastlines, and the Americas have only two nations without access to open oceans. […]
Is there a relationship between porosity and permeability?
Is there a relationship between porosity and permeability? More specifically, porosity of a rock is a measure of its ability to hold a fluid. Permeability is a measure of the ease of flow of a fluid through a porous solid. A rock may be extremely porous, but if the pores are not connected, it will […]
Can I paraphrase a citation?
Can I paraphrase a citation? When you use your own words to convey information from an original source, you are paraphrasing. While paraphrases do not require quotation marks, they do require citations. Be sure to change both the words and word order of the original source in order to avoid plagiarism. Why do you still […]
Will ice melt at 2 degrees?
How do you tell if my fuel filter is clogged?

The most common sign of a clogged fuel filter is trouble starting the car, since it depletes the oil supply going to the engine. Issues Accelerating. Frequent Idling and Sputtering. Strong Odors. Engine Misfires/Low Performance. […]
How does a car know when airbags deploy?
How does a car know when airbags deploy? Here’s how they work: Sensors in the car detect when an impact has happened. The sensors send a signal indicating sudden deceleration to a computer inside the car. Airbags won’t deploy in low-speed crashes in which seatbelts alone should provide enough protection. At what speed do airbags […]
