General knowledge important Question Answer
In today's time, it has become very necessary to have knowledge of general knowledge. If we explain the word GK, then the knowledge of the whole world is absorbed in this GK word. General knowledge is to get general information, but it is not easy to get knowledge of general knowledge, you can get general knowledge even by living in TV, internet or society.
You do not have to waste your time here and there, so here are the most important questions of general knowledge for you and their answers are also given. Along with general knowledge, if you are preparing for any exam like IAS, PCS, SBI, IBPS, RRB, RPF, NTPC, SSC, UPSC, Railway, NDA, RAS, BPSC, JPSC, CDS, Banking Exams or For any Government Exam, the questions of general knowledge and their answers have been presented to you especially for them.
We will continue to present before you the questions of general knowledge related to foreign countries and all kinds of information and their answers.
Here are very important questions of General Knowledge and their answers, which will be very helpful in increasing your general knowledge.
General knowledge important Question Answer
Q1 - Are mountains colder than flat?
Answer: The air pressure on the mountains is low, so the temperature is also low.
Q 2 - Why red color is used for danger sign?
Answer - Red light has the highest wavelength. For this reason the scattering of red colored rays is minimal. Even when the weather is not clear, the red colored sign can be seen from far away as well. For this reason red color is used.
Q 3 - Days are bigger in summer than in winter and nights are shorter, why?
Answer - Earth is tilted on its axis 23-10 / 2. Due to this, the rays of the sun fall perpendicular to the curb line during the summer season. Therefore, these days the regions of India remain light for a long time. For this reason, the days are bigger and the nights are shorter in the summer than in the winter.
Q 4 - Ice buried in wood dust melts late. Why?
Answer: Wood powder is a bad conductor of heat. For this reason, keeping snow covered with sawdust is not an immediate mistake.
Q 5 - If the bottle water is completely filled with water and tightly frozen, if it freezes at night or in the fridge, why does the bottle break?
Answer - The freezing point of water is 0 ° C, but when the temperature of water descends from 4 ° C to 0 ° C, its volume increases instead of decreasing, hence the volume of ice at 0 ° C is the same amount of water. The volume of the water is higher than the volume of the bottle, when the water of the bottle accumulates, the volume of its water increases, as a result, the bottle bursts due to not having space to accommodate that volume.
Q 6 - The food cooks quickly in the pressure cooker, why?
Answer: Things get cooked fast in excess temperature. Evaporation occurs by having water in the pressure cooker. Due to which the pressure increases, as well as the boiling point of water increases, the temperature inside the cooker increases due to increase in boiling point, which causes the food inside the pressure cooker to cook quickly.
Q 7 - Why is the well's water warm in winter and cold in summer?
Answer - The land is a bad conductor of heat, so in summer, the temperature of the atmosphere does not reach inside the earth and in winter, the temperature of the earth does not come up. This is the reason that the water of the well is hot in winter and cold in summer.
Q 8 Diamond is the conductor of electricity, while graphite is the conductor, why?
Answer - This happens because of the crystalline structure of diamond and graphite, as we know that the transport of electric current is actually the transport of electrons, so any element whose crystalline structure will be very dense. It will not have space between atoms for electron transport, the fact is with diamond. In diamond, an atom of carbon is surrounded by four of its atoms and all its valencies are satisfied and therefore there is space for transfer of electrons between its various surfaces. In contrast, an atom of carbon in graphite is surrounded by three atoms of the same element and thus the valencies of carbon are not satisfied, so there is enough space available for electron transfer. This is why graphite is a conductor of electricity and a diamond conductor.
Q 9 - Why do water pipes rupture in cold weather?
Answer: In cold weather, the temperature of water drops, due to which the water starts to freeze in the pipe, and its volume increases but the volume of the pipe remains the same, so due to the pressure of ice, the pipe breaks.
Q 10 - The sky appears blue, why?
Answer - The spread of color radiation is inversely proportional to the fourth power of wavelength, since blue color
The wavelength is the lowest, so the spread of blue is the highest, so the sky appears blue.
