What is an example of a isolated system? A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. An isolated system does not exchange energy or matter with its surroundings. Is an isolated system? In physical science, an isolated system is either […]
Does higher volume mean higher density?
Does higher volume mean higher density? Density is determined by an object’s mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density. It is about how heavy something is compared to the same amount (volume) of water. Are volume and mass […]
Why do mid-latitude cyclones finally die out?
Why do mid-latitude cyclones finally die out? All mid-latitude cyclones eventually weaken and dissipate. This can happen for a combination of the following reasons: loss of access to warm air, loss of access to moisture, occlusion of cooler/drier air around the low. Generally, the cold front moves faster than the warm front. How long do […]
What is the relationship between different trophic levels?
What is the relationship between different trophic levels? The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and […]
What are 3 adaptations that allow plants to survive on land?
What are 3 adaptations that allow plants to survive on land? Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue. What challenges did plants have to overcome to live on land? The life on land presents significant challenges for plants, including the potential for desiccation, mutagenic […]
What are the types of digest?
What are the types of digest? Digestion is often broken down into two types: Mechanical digestion — food is physically broken into smaller parts. For instance, by chewing. Chemical digestion — food is broken down by acids and enzymes into its basic units. What are the six steps of the digestive system? The processes of […]
What happens when you add a proton to hydrogen?
What happens when you add a proton to hydrogen? Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen […]
What is the full form of LCD?
What is the full form of LCD? A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Who invented logo? Wally Feurzeig Who logo means? WHO’s emblem was chosen by the First World Health Assembly in 1948. The emblem consists […]
What are the examples of force change in size?
Does rubber neutralize electricity?
Does rubber neutralize electricity? Rubber is an insulator. Electricity will always travel “the path of least resistance.” Rubber has a very high resistance, so electricity will go somewhere else to find ground. It doesn’t neutralize electricity. It has a high electrical resistance, making it very difficult for electricity to pass through it. Can insulators prevent […]
