What temperature rise are we on track for? Greenhouse gas emissions reached a new high last year, putting us on track for an average temperature rise of 3 degrees Celsius. COVID-19 lockdowns are likely to result in just a 0.01C reduction in global warming by 2050. How fast is the global temperature rising? According to […]

What is the relationship between atmospheric pressure and altitude? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than […]

What are disadvantages of fertilizers? Fertilizers have the following disadvantages: They are expensive. The ingredients in the fertilizers are toxic to the skin and respiratory system. Excessive use of fertilizers damages the plants and reduces soil fertility. Leaching occurs and the fertilizers reach the rivers causing eutrophication. What is the main disadvantage of using inorganic […]

Who discovered positive and negative charges? Benjamin Franklin What is charge and write its properties? The charge is a scalar quantity as it has only magnitude and no direction. The charge is just as other fundamental properties of the system like mass. The only difference between mass and charge is that charge is both positive […]

Is laser light hotter than white light? Laser Light Is Hotter Than White Light. What are three differences between light from an incandescent bulb and light from a laser? A laser generates a beam of very intense light. The major difference between laser light and light generated by white light sources (such as a light […]
