Do things float better in hot or cold water? Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water. […]
What is biogeochemical cycle give two examples?
What is biogeochemical cycle give two examples? Biogeochemical cycles are basically divided into two types: Gaseous cycles – Includes Carbon, Oxygen, Nitrogen, and the Water cycle. Sedimentary cycles – Includes Sulphur, Phosphorus, Rock cycle, etc. Which biogeochemical cycle is least dependent on biotic processes? Explanation: The slowest biogeochemical cycle, the phosphorus cycle doesn’t have a […]
Which contributes the most to biodiversity loss?
Which contributes the most to biodiversity loss? climate change What are the two main benefits of protecting entire ecosystems? In essence, conservationists are able to preserve large areas to promote and ensure adequate sources of food, mates, and shelter, by protecting habitats. This is a more productive way to offer protection to threatened populations, and […]
What is the character in hybridization of carbon when it exerts strongest effect a 25% B 50% C 75% D 100%?
What is the character in hybridization of carbon when it exerts strongest effect a 25% B 50% C 75% D 100%? The correct option is (b) 50%. This is because, in any hybridisation, there is no feasibility to have s character more than 50%. Thus, maximum -I effect is shown by sp hybridisation having 50% […]

What are the 2 types of electricity?
What are the 2 types of electricity? There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. What is better AC or DC? DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to […]
Can atoms fuse together?
Can atoms fuse together? To make atoms fuse, we have to heat them up to make plasmas (ultra-hot soups of gases in which the atoms get so hot that they’re blown apart into their constituent nuclei and electrons), then hold them tightly together in a confined space at temperatures at least as hot as you […]
How is carbon-14 used in medicine?
How is carbon-14 used in medicine? Carbon-14, which is radioactive, is the isotope used in radiocarbon dating and radiolabeling. medically important radioactive isotope is carbon-14, which is used in a breath test to detect the ulcer-causing bacteria Heliobacter pylori. Why is carbon 14 not used in nuclear medicine? Answer: It is all to do with […]
What is the main function of steering system?
What is the main function of steering system? basic function of the steering system is to allow the driver to safely and precisely steer the vehicle. Beyond this, the steering system also provides a way to reduce driver effort by making the act of steering the vehicle easier. What are the 5 functions of a […]
